Conductive plastics are generally divided into two categories: structural and composite conductive plastics. The synthesis process of structural data is complex and costly, and now it is quite expensive. It is a truly conductive plastic. Once the development breaks through the technical bottleneck, it will bring unimaginable impacts to our lives.

Composite type is composed of conductive substances and polymer materials. This category has a slightly lower cost and can meet various molding requirements, making it a widely used functional polymer material. This metal like plastic is a composite conductive polymer material. It is made by doping certain ions with high polymer plastics such as polyethylene, polypyrrole, polysulfine, and polyaniline, and undergoing special treatment and reaction. It has the advantages of both conductors and plastics.

Scientists believe that plastic is a polymer with many carbon and hydrogen atoms in its molecules, which are connected hand in hand to form a long chain. Carbon atoms have the ability to "pull" one or several electrons from each other. Pulling a few carbon atoms with electrons, the ability to control electrons is relatively weak, and they are easily taken away by dopants, leaving vacancies. This is like a parking lot crowded with cars, once one car leaves the exit, another car can enter. When a certain voltage is applied from the outside, electrons near vacancies in polymer molecules will enter the vacancies and form new vacancies, which alternate and continue to form current flow.

A plastic battery made of conductive plastic works much like a sponge absorbing water, and during discharge, the electrodes expel electrons; When charging, the electrode also adsorbs electrons. In this way, the electrode will not react chemically with the solution and dissolve. Therefore, the charging and discharging time is fast and the lifespan is long. Using it as a car power can greatly improve speed and hill climbing function; Weaving it into the lining of clothes can generate heat and prevent cold, replacing down jackets; Using it to make room wall panels can actively adjust the room temperature; It can even be used to drive electronic computers.

Conductive plastics also have other "tricks": in displays, they can cause themselves to change color; In the anti electromagnetic wave jamming device, there is the ability to absorb electromagnetic radiation; It can also deal with static electricity in industries such as electronics, chemicals, and precision instruments. Japan has also developed a floor material containing carbon aluminum alloy conductive fibers and conductive plastics, which can be moved, assembled, poured, and bonded. Installing this type of floor will allow static electricity from the human body to run underground, without posing any danger to people or machines.
