▎ 摘　　要

NOVELTY - Marine anti-corrosion and anti-fouling composite material comprises 0.1-30 wt.% graphene-based powder, 0.1-10 wt.% metal oxide powder, 1-80 wt.% polymer polymer and 0.1-10 wt.% curing agent. USE - Marine anti-corrosion and anti-fouling composite material. ADVANTAGE - The marine anti-corrosion and anti-fouling composite material realizes synergistic anticorrosion and antifouling by mixing graphene-based powder, metal oxide powder macromolecular polymer and curing agent, and integrating functions. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: 1. a method for preparing marine anti-corrosion and anti-fouling prepreg, which involves: a. providing marine anti-corrosion and anti-fouling composite material; and b. coating marine anti-corrosion and anti-fouling composite material into film, and subjecting to heating and curing treatment to prepare marine anti-corrosion and anti-fouling prepreg; and 2. a method for using marine anti-corrosion and anti-fouling prepreg, which involves: a. attaching marine anti-corrosion and anti-fouling prepreg below contact surface of ship and seawater for ship anti-corrosion.
