SEMICONDUCTIVE POLYIMIDE FILM AND PROCESS FOR PRODUCTION THEREOF

摘要

A polyamic acid solution and/or a polyamic acid gel film is subjected to at least one treatment selected from among addition of a semiconductive inorganic filler,addition of an electroconductivity−imparting agent,and formation of a conducting film;and then the polyamic acid contained in the resulting solution or film is subjected to imidation.The semiconductive polyimide film thus produced is well controlled in surface resistance and volume resistance with reduction in the voltage dependences of both resistances,has excellent mechanical characteristics,and realizes a high elongation.
