▎ 摘 要
NOVELTY - Method for preparing a mini-graphene aerogel device comprising a mini-graphene aerogel unit involves using graphene oxide solution as ink, printing on the substrate of the device, curing, adding the polar solution containing foaming agent, plasticizing graphene oxide and foaming, drying, reducing to obtain mini-graphene aerogel unit on the device substrate. USE - The method is used for preparing a mini-graphene aerogel device which is used for sensing and energy storage. ADVANTAGE - The method produces micro-sized graphene aerogel array device with excellent flexibility, extremely high stability, high accuracy, reliability, provides machine intelligent learning and recognition functions, and promotes the development of the next generation of artificial intelligence. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a mini-graphene aerogel device comprising mini-graphene aerogel units, and mini-graphene aerogel units constitute an array.
