Preparation, characterisation and properties of nanocomposites based on epoxy resins - an overview

An overview about the use of nanoparticles in epoxy resins is given. Deaggregated fumed silica, sot gel materials and other spheroidic nanoparticles improved the abrasion resistance and the mechanical properties of filled epoxides, and several properties can be improved by specific particles. Combustion properties, strength and permeation can be improved by organically modified layered silicates. The proper characterisation of the nanocomposites is still an art. TEM analysis of the cured materials and light scattering with 3D cross-correlation for the liquid samples were sufficient methods for the characterisation of filled epoxides.
