charged body having negative electric charge and artificial generator comprising the same

摘要

The present invention relates to a negatively electrified body and a triboelectricity generator including the same. According to the present invention, the negatively electrified body includes a polymer including a repeating unit represented by one among predetermined chemical formulas 1 to 5. Also, the polymer is a homopolymer including the repeating unit represented by the corresponding chemical formulas. The negatively electrified body utilizes a novel structure to significantly enhance the charge generation efficiency and dielectric constants.
