In order to improve the dispersion properties and interfacial bonding properties of nano carbon fibers (NCF) in epoxy resins. Here, we report a facile method by using gelatin as a biosurfactant to treat nano carbon fibers (gelatin-NCF) for preparing multifunctional NCF/EP composites. Moreover, the mechanical properties and thermal stability of NCF/EP composites were investigated in this work. The results show that gelatin-NCF improve the properties of epoxy composites more effectively. Gelatin improves the dispersion of carbon fibers through non-covalent treatment. Furthermore, the functional group on the surface of gelatin can promote the interface between the nanofiller and the epoxy resin, which provides better mechanical properties. Studies have shown that gelatin is a promising green biosurfactant that can be used to prepare multifunctional polymer nanocomposites. |
