▎ 摘　　要

NOVELTY - Preparing carbon fiber composite material comprises adding scale inhibitor to graphene oxide solution to obtain scale inhibitor graphene oxide solution, adding carbon fiber to scale-inhibiting graphene oxide solution, and performing wet treatment to obtain carbon fiber composite material. USE - The method is useful for preparing carbon fiber composite material in filter cartridge for water purification (claimed). ADVANTAGE - The material has better anti-scale performance for water purification. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for filter cartridge, comprising carbon fiber composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of flow chart for preparing carbon fiber composite material. (Drawing includes non-English language text).
