▎ 摘　　要

NOVELTY - A reduced graphene oxide-p-phenylenediamine/thermoplastic polyurethane composite film is prepared by polymerizing p-phenylenediamine on oxidized graphene in an ice water bath, reducing by hydrazine hydrate, dispersing in dimethylformamide, ultrasonically processing, and pouring thermoplastic polyurethane in dimethylformamide using solution coating process. USE - Reduced graphene oxide-p-phenylenediamine/thermoplastic polyurethane composite film for water storage bag, oil storage bag and instrument package (claimed). ADVANTAGE - The reduced graphene oxide-p-phenylenediamine/thermoplastic polyurethane composite film has excellent electrical and thermal conductivity, and greatly prolonged small molecular substance through a passage composite film.
