▎ 摘　　要

NOVELTY - Preparation of graphene electrode nano-generator comprises irradiating back of polyimide film with carbon dioxide laser in laser cutting machine to obtain two LIG electrodes with a preset shape, taking the PI film with two LGL electrodes as a friction layer, selecting electropositive friction material with a contact charge as a sliding layer, and preparing graphene electrode nanorgenerator. USE - Preparation method of graphene electrode nano-generator e.g. triboelec tricnanogenerator (TENG). ADVANTAGE - The method simplifies the preparation process of the nano-generator, reduces the production cost, and avoids the damage of the metal electrode to the soil and environment, has good output performance, and has great application potential in realizing sensor self-supply energy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene electrode nano-generator. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of the graphene electrode nano-generator. Sliding layer (2) Lig (3)
