The Sick Truth of Does Plastic Conduct Electricity

Does plastic conduct electricity? The answer may surprise you – it depends on the type of plastic. Some plastics are excellent electrical insulators, while others are quite good conductors. The key difference lies in the way that the atoms in the two materials are arranged.

In this blog post, we will discuss do plastic conducts electricity, some exciting facts about electrically-conducting plastic, and different types of conducting and non-conducting plastics. Let’s dive in!

However, some plastics are conductors of electricity because the atoms are arranged in such a way that electrons can move freely. This allows electrical current to flow through the material. So, when it comes to electricity, not all plastics are created equal.

Plastic That Conducts Electricity

Usually, we’ve been taught that plastic does not conduct electricity, but a team of Australian researchers at the University of New South Wales might have just changed that. In a recently published paper, they detail a technique that can make almost any plastic film electrically-conductive, and even give some plastics superconducting properties.

The implications of this discovery are far-reaching and could lead to major advancements in the fields of electronics and energy. For example, imagine phones and laptops that can be charged wirelessly, or batteries that last 10 times longer than they do now. The potential applications are endless and we can only wait to see what comes next from this ground-breaking research.

Today, most electronics are built on a foundation of silicon, a brittle material that doesn’t play nice with other substances. This has led scientists to search for alternatives that are more compatible with the diverse set of materials used in today’s devices. One promising option is plastic, which is lightweight, flexible, and inexpensive. However, plastic has one major drawback: it is an insulator, meaning it does not conduct electricity. This makes it unsuitable for use in many electronic devices.

Fortunately, scientists have developed a way to make plastic conductive. By adding a small amount of carbon to the polymer structure, they are able to create a material that is both electrically conductive and mechanically flexible. While this may sound like the perfect solution for the ever-growing world of electronics, there are some significant drawbacks to using conductive polymers.

For one, they are not as efficient at conducting electricity as traditional metals like copper or aluminum. In addition, they are not well suited for high-temperature applications. As a result, conductive polymers are currently only used in very specific applications such as electrostatic discharge protection and antistatic coatings.

There are also specific polymer materials, like polyaniline, polythiophene, and polypyrrole, which can conduct electricity; however, it can be difficult or impossible to change their shape. They are often unstable conductors with low conductivity rates and are intolerant to oxygen exposure and are difficult to process.

This new technique, which has been published in the journal ChemPhysChem by a team led by UNSW‘s Professor Paul Meredith and Associate Professor Ben Powell, doesn’t have those issues. It’s easy to produce and still acts like plastic, but has a high conductivity on par with metals. The discovery could pave the way for the development of inefficient energy storage devices, such as supercapacitors and batteries. It might also lead to the development of ‘smart windows’, which could tint in response to an electric current, or ‘active packaging’, where sensors built into food wrappers could detect when the fruit is starting to rot.

The new material is made of Halcyon, an inexpensive and widely available polymer, mixed with a conducting polymer called PEDOT:PSS. When they combine, the molecules self-assemble into long chains that have alternating regions of insulating and conducting plastic.

As our world becomes increasingly digitized, the demand for conductive plastics has never been higher. These materials are essential for applications ranging from Touchscreens to solar cells, and their conductivity can be precisely tuned to meet the needs of any given application.

The most exciting part of this research is the way that material scientists can precisely alter the materials’ conductivity. “Put simply, we have ten billion options to adjust the recipe when we’re making the plastic film. In theory, we can make plastics that conduct no electricity at all or as well as metals do — and everything in between.”-says researcher Dr. Andrew Stephenson. This level of control opens up a whole world of possibilities for flexible electronics and other cutting-edge applications.

By making an affordable and approachable technique for producing conductive plastics, we could see flexible touchscreens and that oh-so-futuristic e-paper sooner than you might think. With further development, we could see a whole new generation of electronic devices made from these materials. Exciting stuff!

Different Types of Plastics (Conductive & Non-Conductive)

Not all plastics are created equal. Different types of plastics are used for different purposes, and each has its own unique set of properties. The conduction of electricity depends on the structure of the polymer. Plastics like Polyethylene, Polystyrene do not conduct electricity. However, if the polymer is polar, it has a dipole moment which can cause it to be conductive.

1. Polyethylene (PE)

Polyethylene (PE) is a thermoplastic polymer made from the monomer ethylene. It is the most common plastic in the world, being used in everything from packaging to piping. Polyethylene can be either high-density (HDPE) or low-density (LDPE), depending on the amount of long-chain branching in the polymer backbone. HDPE is less flexible and has higher tensile strength, while LDPE is more flexible and has a lower melting point.

Polyethylene is an excellent electrical insulator with high treeing resistance; however, it can become electrostatically charged due to its own properties. This will reduce the number of problems that might occur otherwise if you add graphite or carbon black into your product for additional protection against electricity flow through wires during production processes

2. Polyethylene Terephthalate (PET)

The most common type of plastic is polyethylene terephthalate or PET. This type of plastic is clear and shatter-resistant, making it ideal for food and drink packaging. However, it is not suitable for reuse as it can leach chemicals into food and drink.

The conductivity of a polymer material such as PET may be due to the presence of hydrogen bonds between molecules.

3. High-density polyethylene (HDPE)

High-density polyethylene, or HDPE, is another common type of plastic. It is similar to PET in terms of durability and clarity, but it is also more flexible and less likely to leak chemicals. As a result, HDPE is often used for reusable water bottles and food storage containers.

The addition of 40wt% PANI caused a significant increase in the electrical conductivity of this material.

4. Polypropylene (PP)

Polypropylene, or PP, is a type of plastic that is known for being sturdy and heat-resistant. It is often used for making Tupperware, as well as for industrial applications such as car parts and pipes.

Polypropylene is a great material for electrical applications because of its high dielectric strength and insulation properties. It can be modified to make it conducive or anti-static

5. Polymethyl methacrylate (PMMA)

Acrylic is a clear plastic that has many purposes. It can be used as a substitute for glass in windows, aquariums, and signboards. Acrylic is also used in products such as acrylic paint, picture frames, and shower doors. Polymethyl methacrylate (PMMA) is a type of acrylic that is often used in medical implants and contact lenses.

Poly(methyl methacrylate) is an excellent polymer for making lightweight, stiff materials with good mechanical stability. Polyaniline on the other hand has high conductivity that makes it perfect to be used in electric current generating devices such as batteries or transistors!

6. Polycarbonate (PC)

Polycarbonate (PC) is a strong, durable plastic that has a wide range of applications. It is clear and transparent, making it ideal for eyeglasses and safety equipment.

Polycarbonate is an excellent material to use in water-related environments because it does not conduct electricity. It is also shatter-resistant, making it a popular choice for food storage containers and drinking glasses. Polycarbonate is also used in the manufacture of electronic components and incision instruments.

7. Polyvinyl chloride, or PVC

Polyvinyl chloride, or PVC, is a versatile plastic material that is used in a wide variety of applications. It is made from ethylene and chlorine, and it can be rigid or flexible, depending on the manufacturing process. PVC is strong and durable, making it an ideal material for pipes and tubing. It is also weather-resistant, making it a good choice for outdoor applications such as gutters and siding.

In addition, PVC is lightweight and easy to work with, making it a popular choice for many DIY projects. It has excellent electrical insulating properties, making it a perfect choice for electric cables for residential buildings, vehicles, etc.

8. Acrylonitrile-Butadiene-Styrene (ABS)

Acrylonitrile-Butadiene-Styrene (ABS) is a petroleum-based thermoplastic polymer. It is manufactured by the copolymerization of acrylonitrile and styrene with polybutadiene. ABS is used in a variety of applications, including computer peripherals, auto parts, and toys. It is known for its strength, rigidity, and resistance to impact and heat.

The study showed that when ABS/rGO composites are combined with an ultra-low percolation threshold and higher electrical conductivity, they can provide excellent performance in terms of conduction.

Conclusion

So we know plastic does conduct electricity but not all of them does. In fact, the kind of plastic you use will determine how well it conducts electricity. In general, plastics that contain metal fillers or carbon black tend to be good conductors of electricity. On the other hand, plastics that are pure and have no additives are poor conductors of electricity.
