▎ 摘　　要

NOVELTY - Liquid metal graphene composite conductive paste comprises 20-30 pts. wt. graphene and 70-80 pts. liquid metal, where the mixing ratio of the graphene and the liquid metal in the conductive paste is 1:3, where the liquid metal is gallium, gallium indium alloy, gallium tin alloy or gallium indium tin alloy, the graphene is modified graphene, surfactant used for modifying graphene is sodium dodecyl sulfate, and reducing agent used for modifying graphene is ethylene diamine. USE - Liquid metal graphene composite conductive paste of transparent display screen (claimed) used in city brightening engineering and large screen display system, and also used in large square lighting, stage scenery, bar, high-grade singing hall, city landmark building, municipal building, airport, automobile 4S shop, hotel, bank and brand chain store. ADVANTAGE - The liquid metal graphene composite conductive paste improves the conductivity and radiating performance to satisfy the electric signal transmission requirement of the large transparent display screen, and the service life of the LED lamp. At the same time, the liquid metal is compatible with the glass substrate, which can soak the glass substrates, thus ensuring that liquid metal can be stably adhered on the substrate, and realizing the transmission requirements of the electric energy and electric signal of the LED lamp.
