Preparation of conducting polymer/insulating polymer composite films using molecular self-assembly process

摘要

By exposing low-density polyethylene to anatmosphere of fuming sulfric acid, sulfonated low-densitypolyethylenes (SPE) were prepared and the degree of surfacesulfonation for treated film was determined as the weight-increaseper unit area. Polypyrrole (PPy) films on the surface of SPE weregrew using a molecular self-assembly process. Theelectrochemical properties of PPy/SPE composite films have beeninvestigated and their functional applications have also been proposed.
