Abstract
This work is focused on the preparation and characterisation of high performance multiphase epoxy nanocomposites containing functionalised carbon nanotubes (CNTs) and phase-separating thermoplastic (TP) microparticles. Two epoxy systems with different number of functional groups were employed as the matrix. Analysis of the curing reaction in ternary nanocomposite systems indicated a decrease in the activation energy in comparison with the neat epoxy material. This could be attributed to the catalytic effects of the functionalised nanotubes. TP-rich particles with varying particle sizes are formed in two systems, which is believed to be caused by the differences between viscosities and crosslink densities of the epoxy materials. Although based on microscopic analysis, CNTs are mostly well dispersed, the rather inevitable formation of the secondary agglomerations lead to the non-uniform distribution and irregular shape of TP-rich phase. © CCM 2020 - 18th European Conference on Composite Materials.
