▎ 摘 要
NOVELTY - Preparation of functionalized graphene-based film involves uniformly dispersing functionalized graphene in solvent to form dispersion, coating the obtained dispersion on a substrate, forming a transparent or translucent film, drying, performing high-temperature treatment of the resultant film in protective atmosphere and cooling. USE - Preparation of functionalized graphene-based film used for touchscreen, solar cell and electronic product. ADVANTAGE - The method provides functionalized graphene-based film having excellent light-transmitting property, transparency, electroconductivity and thermal conductivity, by simple and economical process.
