This work is devoted to the study of the effect of carbon nanotubes functionalization on the electrical conductivity of composite materials based on them. Carbon nanotubes were functionalized by treatment in nitric acid and isopropyl alcohol. Changes in the morphology of multi-walled carbon nanotubes during liquid-phase functionalization were investigated using Auger-electron microscopy. Samples of composite material on the basis of initial and functionalized carbon nanotubes and epoxy resin were prepared and the concentration dependence of electrical conductivity using the four-probe method was studied. The study reveals the effect of functionalization in various solutions on the electrophysical properties of the obtained carbon nanotubes/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.

In this work, highly functionalized carbon nanotubes (CNTs) were achieved using plasma inducing-graft technique, in which maleic anhydride (MAH) was used as graft monomer. Then they were introduced into epoxy resin (EP) curing system to obtain CNTs/EP composites. The modification performance of this proposed method was summarized and contrasted with that of argon (Ar) plasma atmosphere. Results show that these two plasma methods can improve CNTs’ surface activity, and corresponding optimum powers are both 60 W. Meanwhile, thin polymaleic anhydride film can be coated on the surface of CNTs during MAH plasma inducing-graft, which can make sure of effectively dispersion and adhesion of CNTs in epoxy. Such treatment can not only obtain highly functionalized CNTs, but also overcome its serious self-entangling and aggregation problem. Compared with those composites modified by argon (Ar) plasma, the mechanical and thermal properties of CNTs/EP composites modified by MAH plasma are greatly enhanced.
