SEMICONDUCTING POLYMERS AND METHODS FOR THE PRODUCTION OF THESE

摘要

A novel type of semiconducting polymer comprising an insulating thermoplastic polymer carrier and an intrinsically conducting polymer (ICP) is disclosed. In this semiconducting polymer essentially each of the ICP mesomers are covalently linked to the carrier, and the content of ICP is 0,5 to 25 % by weight, preferably 1 to 15 % by weight, more preferably 3 to 10 % by weight. The new semiconducting polymer is a material having good mechanical properties (e.g. mechanical properties comparable to well known thermplastics like polyethylen, poly(meth)acrylates, EVA, etc.) and it shows a loss of conductivity during processing which is lower than the conductivity loss of known semiconducting polymer materials. The semiconducting polymer is suitable for use as antistatic coating or EMI-shielding.
