An overview on the interfacial interactions between cnts and the polymer matrix

Because of their nanoscale dimensions, low density, intrinsically superior mechanical properties, and remarkable electrical and thermal properties, carbon nanotubes (CNTs) are expected to be one of the most potential components for the composites. At the same time, more and more people focus on the idea of incorporating CNTs into conventional fiber reinforced polymer composites. Actually the properties of the constituent materials as well as the characteristics of the interface(s) between matrixes and fibers have impacts on the mechanical behavior of composites. The interface between fibers and matrixes has been regarded as a critical element in controlling the overall performance of conventional polymer composites. In this paper, we review recent advances about interfacial interactions between CNTs and the polymer matrix and effect of the geometrical properties of the CNTs on the interfacial behavior of epoxy/CNT composites, including length, diameter, chirality and waviness.
