▎ 摘　　要

NOVELTY - Graphite alkene compound waterproof paper is a composite construction of paper and reduction-oxidation graphite alkene, where reduction-oxidation graphite alkene extexine is reduction-oxidation graphite alkene layer, and one side that reduction-oxidation graphite alkene and paper contacted is oxidation graphite alkene layer. The reduction-oxidation graphite alkene presents the gradient reduction characteristic that reduction degree increases progressively from one side to the extexine with the paper contact. USE - Graphite alkene compound waterproof paper used in waterproof packaging materials (claimed). ADVANTAGE - The graphite alkene compound waterproof paper has excellent waterproofness and durability, and can be prepared in a simple, cost-effective and eco-friendly manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene composite waterproof paper, which involves: (A) dispersing graphene oxide in a solvent for performing ultrasonic treatment and cell crushing to obtain a graphene oxide dispersion liquid; (B) adopting electric field polarization to enable the surface of the paper to be positively charged; (C) paving the paper with the positive charges on the surface of the graphene oxide dispersion liquid to enable one surface of the paper to be completely soaked; (D) drying the impregnated paper; and (E) carrying out heat treatment to obtain the graphene composite waterproof paper.
