Abstract

Fluorinated graphene, a novel member of the graphene family, retains the characteristic two-dimensional layered structure of graphene and exhibits distinctive properties such as hydrophobicity, wear resistance, and electrical insulation. These attributes make it an excellent candidate for enhancing the corrosion and wear resistance of organic coatings. However, improving its dispersibility within resin matrices poses a significant challenge, given that fluorinated graphene often exhibits poor dispersion and a propensity to agglomerate and stack in organic matrices. Achieving a uniform and stable dispersion is crucial for maximizing its anticorrosion effectiveness.

Key words
