Most consumer plastics per se are insulators and conductivity can be imparted in them by adding conductive fillers like carbon blacks, CNT, Graphene etc.
thank you sir, i need a polymer which can be low cost . i am going to composite with metal oxide . kindly suggest me the polymer, both conducting and non conducting polymer
The polymers are conducting in nature if the conjugation is present throughout the polymer chain which allow the delacalization of electron through the chain. The plastics are insulator because of lack of conjugation throughout the polymer chain.
Aniline is one of the cheapest monomer used for synthesis of polymer (polyaniline). The synthesis of polyaniline is also very easy. If metal oxides are added during synthesis of polyaniline, it results in formation of polyaniline-metaloxide composite.
Non-conducting polymers: polyethylene, polypropylene and polytetrafluoroethylene.
I think it is theoretically possible. The way is dehydrochlarination of PVC, one of the most widely used and cheapest thermoplastics. This could yield polyacetylene structure, consisting of conjugated C=C bonds, which is highly conductive. Dehydrochlorination of PVC can be initiated and achieved chemically or thermally.
Yes, in principle dehydrochlorination of PVC might work but it does not result in a flawless polyconjugated structre. Only gradually increasing polyconjugated structures are formed (darker color) together with chain scission. Synthesis of polyacetylenes is much more ecomplicated than that. So far the most potent conducting polymers (industrially) are polyaniline, polypyrrol, polytiophene (sustituted), poly phenylene-vinylene etc. ut these cannot be obtained by the controlled thermal degradation of commercial polymers. One interesting approach was intorduced by Brigitta Bozay in her PhD thesis, where carbon nanofibrous structures were obtained form plastic waste:
