Effects of Carboxyl Functionalized Carbon Nanotube on the Tensile Strength and Wear Resistance of Epoxy Composites

Epoxy resin presents 3D cross-linking network structure characteristics after curing, resulting in a lower wear resistance of epoxy resin, which limits its extensive applications. In this paper, the effects of adding carboxyl functionalized carbon nanotubes on the tensile strength and wear resistance of carbon nanotube/epoxy composites were studied. The results showed that the tensile strength and wear resistance of the composites were effectively improved through carboxyl functionalization of carbon nanotubes.
