Problems solved by technology

Polyaniline has been widely studied and applied because of its easy-to-obtain raw materials, simple synthesis process, and good chemical and environmental stability; polyaniline film is a conductive film, which is widely used in solar cells, electrode materials, displays, etc. Among various optoelectronic materials, however, at present, commercially available polyaniline films have poor heat resistance stability, and in order to improve their heat resistance performance, high heat resistant inorganic fillers are often added therein, because the compatibility between inorganic fillers and polyaniline is poor , which will easily reduce the mechanical stability of the film
