POLYANILINE CONDUCTOR DOPED WITH SULFONATED POLYPHENYLSILSESQUIOXANE AND DOPANT TO HAVE POSITIVE TEMPERATURE COEFFICIENT RESISTANCE, AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a polyaniline conductor doped with sulfonated polyphenylsilsesquioxane and a dopant to enable having a positive temperature coefficient resistance. When doped in a polyaniline, the sulfonated polyphenylsilsesquioxane allows the doped polyaniline to have high heat resistance and a negative temperature coefficient resistance. It is possible to control the temperature coefficient resistance of a doped polyaniline by simultaneously doping sulfonated polyphenylsilsesquioxane to have a negative temperature coefficient resistance and a dopant to have a positive temperature coefficient resistance.
