▎ 摘  要

NOVELTY - Preparing high stretchability high wrinkle graphene oxide paper, comprises (1) ultrasonically dispersing graphene oxide suspension for 1-2 hours, pouring into a petri dish covered with a filter membrane, placing the petri dish in a 60-80℃ oven to dry for 1-3hours, and continue drying for 1-3 hours, and cooling to room temperature naturally to obtain the first layer of graphene oxide paper, (2) continuing to pour the same volume of graphene oxide suspension on the first layer of graphene oxide paper, and placing the petri dish in a 60-80℃ oven to dry for 1-3 hours and taking out, (3) pouring the divalent metal ion salt solution into the petri dish, soaking for 10-20 minutes, pouring out the solution, drying the petri dish at 60-80℃ for 5-10 minutes, taking the dried paper film out of the petri dish, that is, 2 layers of high wrinkled graphene oxide paper are obtained, and obtaining 20 layers of graphene oxide paper with high stretchability and high wrinkle. USE - The method for preparing high stretchability high wrinkle graphene oxide paper and used in sensor, composite material, protective coating and super capacitor. ADVANTAGE - The prepared graphene oxide paper has excellent tensile property and high fold, at the same time, it has high specific surface area. The solution used in the preparation process is efficient and simple, the preparation period is short, and does not need high temperature environment.
