Fabrication of triboelectric polymer films via repeated rheological forging for ultrahigh surface charge density.

ABSTRACT: Triboelectric polymer with high charge density is the foundation to promote the wide range of applications of triboelectric nanogenerators. This work develops a method to produce triboelectric polymer based on repeated rheological forging. The fluorinated ethylene propylene film fabricated by repeated forging method not only has excellent mechanical properties and good transmittance, but also can maintain an ultrahigh tribo-charge density. Based on the film with a thickness of 30 μm, the output charge density from contact-separation nanogenerator reaches 352 μC·m^-2. Then, the same film is applied for the nanogenerator with air-breakdown mode and a charge density of 510 μC·m^-2 is further achieved. The repeated forging method can effectively regulate the composition of
