▎ 摘　　要

NOVELTY - Preparation of fluorinated graphene/titanium dioxide composite anti-corrosion filler, involves: 1) dispersing graphene oxide in distilled water, followed by ultrasonically processing; 2) mixing prepared solution with fluorotitanate solution and boric acid solution uniformly; 3) transferring the mixed solution into polytetrafluoroethylene lined hydrothermal kettle, performing hydrothermal reaction; 4) washing obtained product by distilled water and drying. USE - Method is used for preparing fluorinated graphene/titanium dioxide composite anti-corrosion filler used in epoxy coating (claimed). ADVANTAGE - The method enables to prepare fluorinated graphene/titanium dioxide composite anti-corrosion filler in which the titanium dioxide grows on the fluorinated graphene in situ, and the two components overlap each other to form an interlayer point-like filling structure. The prepared filler has excellent barrier properties and anti-corrosion properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the fluorinated graphene/titanium dioxide composite anti-corrosion filler.
