Preparation, Characterisation and Properties of Nanocomposites Based on Epoxy Resins – An Overview

Abstract

An overview about the use of nanoparticles in epoxy resins is given. Deaggregated fumed silica, sol 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.

Hotmelts with improved properties by integration of carbon nanotubes

“…To achieve the reinforcing properties a preferably homogenous dispersion of the nanofiller within the polymer is required. [8,[13][14][15] Different authors have reported on the behaviour of CNTs in polymeric matrices and about their tendency to remain in micrometer sized bundles and agglomerates. [11,[16][17][18] Mechanical tests have shown that the existence of primary agglomerates of filler material negatively affects the mechanical properties of the composites since they act as imperfections.…”

“…In the case of a homogenous dispersion an improvement of mechanical properties can be achieved [19] . At a particular concentration an increase in CNT dispersion can also improve electrical conductivity [15,[20][21][22][23][24][25][26] .…”

Spheroidal Nanoparticles in Epoxide‐Based Adhesives

“…Cyclohexene oxide and 3,4‐epoxycyclohexylmethyl‐3',4'‐epoxycyclohexane carboxylate were used as monomers and 3,4‐epoxycyclohexylethyltrimethoxysilane (ECHTMO) as the silane 10, 84. Besides this detailed description, an overview is available 85…”

Nanocomposite Coatings: Preparation, Characterization, Properties, and Applications

“…The small size of the nanoparticles exhibits some advantages since it enables penetrating into ultrasmall holes, indentation, and capillary areas in the polymer matrix. For example, the incorporation of nanoparticles into epoxy resins showed an enhancing of the integrity and durability of coatings thanks to the filling up of microcavities and cracks in the coatings [164][165][166][167]. Nanoparticles can also prevent disaggregation of the polymer during curing, leading to a homogenous coating.…”
