New Conductive Polymer Nanocomposites

Conductive polymer, also called conductive polymer, refers to a polymer that can make the conductivity within the range of semiconductors and conductors by doping or other means. Usually refers to the intrinsically conductive polymer, this type of polymer backbone contains alternating single and double bonds, thus forming a large conjugated π system. The flow of π electrons creates the possibility of conduction.

The conductive polymer that has not been doped is very low in electrical conductivity and is an insulator. The reason for this is that the energy gap of the conductive polymer is very wide (instability of one-dimensional semiconductors), and that the anti-bonded orbital (void) is substantially free of electrons at room temperature. However, after oxidative doping (making the main chain lose electrons) or reductive doping (making the main chain get electrons), a new polaron, bipolaron, or soliton energy level is generated in the original energy gap, and its electrical conductivity can be Rise to 10 to 10000 S/cm2 to reach the conductivity range of semiconductors or conductors.

Conductive polymers not only have higher electrical conductivity but also have more specific electrical properties, non-linear optical properties, luminescence and magnetic properties, are more flexible, have lower production costs, and have high energy efficiency. Conductive polymers have broad application prospects and application value not only in industrial production and military industry, but also in the conductive polymer doped with magnetic particles to prepare coatings, and can be adjusted by adjusting the composition of conductive polymers and magnetic particles The conductivity and magnetic properties.

Taking an electrode of a watch lithium battery as an example, in an ideal situation, the electrode manufacturing material should be small enough, because no one wants to tie a bulky watch on the wrist, and they also have enough power to ensure that the watch can run for a long time. “Mxenes has great potential for energy storage. Its volumetric capacitance is much higher than that of conventional carbon-based electrodes or graphene electrodes, so it will be widely used in energy storage devices such as wearable devices,” said Dr. Michel Basoth. Energy storage devices, at the same time, the hydrophilicity of the material makes it useful for water treatment systems, such as water purification or desalination membranes, and because the material is very flexible, it can also be used in aerospace components.The research team will next study different proportions of mxene. The effect on material properties and the application of this material.
