▎ 摘 要
NOVELTY - Preparing high-elastic graphene film involves adding 6-10mg/mL oxidized graphene in the aqueous solution, allowing the obtained solution to the naturally airing to form graphene oxide film having thickness of less than or equal to 5 mu m, reducing in the hydroiodic acid aqueous solution and washing with ethanol to remove excess hydroiodic acid. The obtained product is dried naturally and sintered in the graphite furnace at 600-1700 degrees C to obtain graphene film without fold and elastic. USE - Method for preparing high-elastic graphene film used for conductive conduction. ADVANTAGE - The method enables to prepare high-elastic graphene film has good flexibility as repeatedly more than 10 times without leaving trace, fast recovery shape, resisted bending repeatedly for 1 times, horizontal elastic elongation at break of 30-50%, elastic vertical compressing rate of 80-90% and conductivity of 400-7000siemens/cm.
