Review on carbon fiber surface modification using electrophoretic deposition of carbon nanotubes and graphene oxide

Carbon fiber (CF) surface has few polar functional groups, and hence is chemically inactive, leading to weak interface bonding strength with the matrix in composites. Aiming at this problem, this article reviewed the latest research progress in carbon fiber surface modification with electrophoretic deposition of carbon nanotubes and graphene oxide to improve the mechanical properties of composites. Based on the adoption of the electrophoretic deposition processes, the work on carbon fiber surface modification with carbon nanotubes and graphene oxide and the effect of the fiber modification on mechanical properties of modified carbon fiber and their composite materials were described. The factors affecting the effect of electrophoretic deposition on modified carbon fibers were summarized, and corresponding suggestions were put forward. The research trend in carbon fiber surface modification based on the use of electrophoretic deposition was explained, and the paper pointed out that pretreatment of carbon fiber, carbon nanotubes and graphene oxide, and the addition of auxiliary electrophoretic deposition equipment manufacturing will become an important research direction in the future.
