Abstract
The present invention provides a polyimide-based copolymer and electronic component and field effect transistor comprising the same. The polyimide-based copolymer comprises a copolymer of dianhydride and heterocyclic diamine, wherein the heterocyclic diamine has two benzene rings, and there are two ether bonds, two thioether bonds, or one ether bond and one thioether bond between the two benzene rings. The novel polyimide-based copolymer of the invention has excellent thermal-mechanical stability, has potential application prospects, and can be used as a substrate for flexible electronics.
