Construction of hierarchical “organic-inorganic” structure by self-assembly to enhance the interfacial properties of epoxy composites

The “organic-inorganic” hierarchical structure was constructed by self-assembled MXene and chitosan (CS) on carbon fiber (CF) to promote the interfacial performance of CF/epoxy composites. The interfacial adhesion was greatly boosted because of enhanced wettability and surface energy generated by active groups of MXene and CS. The increased roughness caused by the two-dimensional layer structure of MXene gave rise to better mechanical...
