▎ 摘　　要

NOVELTY - Preparation of a hydrophobic graphene conductive material involves: 1) adding graphene oxide to methyl cyanide (CH3CN) solution, followed by ultrasonically dispersing to form graphene oxide dispersion solution; 2) sequentially adding an alkaline reagent, a photocatalyst and a fluoridation reagent into the graphene oxide dispersion liquid, stirring uniformly, reacting under light, filtering, washing, and freeze-drying to form fluoridized graphene oxide; 3) adding fluorinated graphene oxide into deionized water, ultrasonic dispersing, adding hydrazine hydrate, uniformly mixing, reacting, filtering, washing and drying. USE - The method is used for preparing hydrophobic graphene conductive material used for preparation of hydrophobic conductive flexible composite film. ADVANTAGE - The process is carried out under normal temperature and normal pressure by under the photocatalysis condition, without causing any damage to the conjugated structure of the graphene. The prepared product has improved hydrophobic and conductive performances. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of hydrophobic conductive flexible composite film. The method involves adding the prepared hydrophobic graphene conductive material into a dimethyl formamide (DMF) solution, performing ultrasonic dispersion, swelling the material by adding thermoplastic polyurethane (TPU) particles, then stirring until the mixture is uniformly mixed, coating the mixture on a smooth glass plate and drying.
