NOVELTY - Preparing pleated graphene oxide film involves dispersing graphene oxide in first organic solvent uniformly to obtain graphene oxide dispersion liquid; pouring graphene dioxide dispersion solution in supporting component with hole, and filtering to obtain graphene oxide membrane adhered on supporting component; removing first organic solvents in graphene membrane, and placing graphene oxide membrane placed in second organic solvent, and removing second organic solvents from second organosilicone solvent to prepare pleated graphene oxide membrane. USE - Method for preparing pleated graphene oxide film used for water purification and other related fields, environment, resource, energy, etc. ADVANTAGE - The method is simple and easy, is not needed any modifier, crosslinking agent, intercalator or other additional modifier, and provides pleated graphene oxide film with regular ordered two-dimensional structure and excellent performance of nanofiltration of separating.
