One‐Step Fabrication of Transparent and Flexible Nanotopographical‐Triboelectric Nanogenerators via Thermal Nanoimprinting of Thermoplastic Fluoropolymers

Using thermal nanoimprinting, a novel transparent and flexible nanotopographical triboelectric nanogenerator (TENG), with simultaneous nanoreplication and integration of the contact layer with the electrode layer, is first demonstrated. It is expected that the present rapid one-step fabrication methodology well give "disposability" to the TENG with extremely reduced manufacturing costs, which may allay commercialization concerns.
