However, unlike zinc, the oxidized form of the polymer remains insoluble to the corrosive environment and remains intact on the metal surface. Among various polymers, poly(3-hexylthiophene) (P3HT) has most often been used as the active semiconducting layer in CP-FET owing to its high mobility. It can be seen that the coefficient of friction is statistically significant between coated and uncoated fibres; conducting polymer coating decreases the coefficient of friction. In addition, conducting polymer field-effect transistor (CP-FET) platform is a promising technology for low-cost, large-area, and flexible electronics in displays and sensors. The absence of pinholes, cracks, and other coating defects guarantees effective protection. The thermally conducting segment is projected to grow at a higher CAGR due to increasing miniaturization of electronic components requiring advanced and compact conducting polymers for conduction of heat in confined space. Membranes of this type are obtained mainly from the polymers mentioned within Table 1, but considering the number of citations from the literature, the most used polymers are polyaniline (PANI) and polypyrrol (PPy). One can distinguish between three types of conducting polymers: • Electron-conducting polymers • Proton-conducting polymers • Ion-conducting polymers Each polymer type has already found widespread use in many, mainly optical and electronic applications such as batteries, 0000080483 00000 n 24 Condensation Polymerization • In condensation polymerization, a small portion of the monomer molecule is not incorporated in the final polymer. Conducting polymers such as PANi, PPy, and PTh have higher capacitive output, surface area, and flexibility; however, conducting polymers based materials suffer from mechanical stability and cycle-ability. This mechanism is similar to the protection mechanism of zinc to iron. However, the specific capacitance values, potential ranges, long-term stabilities, and cycle lives of supercapacitors based on polymers have been shown to be rather moderate. In a periodic oxidation–reduction cycle, only quasi-stable oxidized and reduced polymers can be expected. Polyheterocycles such as polythiophene or polypyrrole are synthesized by both chemical and electrochemical polymerization. • The monomers are held together by a certain kind of bond (such as an amide bond) and a molecule is eliminatedin the process (such as a water molecule). E.g- Polyacetylene, Polythiophene, Polyaniline,Polypyrrole etc. After the in situ chemical polymerization of aniline monomers, PANI was produced and formed a uniform coating layer around the CNTs.

A platinum electrode coated with polymer in acetonitrile showed the transition between neutral and oxidized state at +1V versus a platinum quasi-reference electrode and the transition between neutral and reduced state at –1.8V. Conducting polymers, such as polypyrrole (PPy), polyaniline (Pani), polythiophene (PTh) and their derivatives, have been used as the active layers of gas sensors. The changes in coefficient of friction of the single fibres upon coating with the conducting polymer are presented in Fig. But in the case of a new class of materials, the conductivity was an intrinsic property. For example, p-type conducting polymers such as poly(3,4-ethylenedioxythiophene) and polypyrrole, can transition from semi-conducting to metallic in response to increasing levels of anions inserted into their structure. This is because the conducting polymer coating layer partially covers the scales and forms a transition hump at the scale tips, which smooths the fibre surface. In addition, conducting polymer field-effect transistor (CP-FET) platform is a promising technology for low-cost, large-area, and flexible electronics in displays and sensors.
