Preparation and investigation of properties of metal-containing nanocomposites on the basis of epoxy diane resin

The influence of additions of nanofillers (NF) containing nanoparticles of copper and zinc oxides, stabilized by a polymer matrix of high pressure polyethylene, prepared by mechanochemical method on peculiarities of structure and properties of the metal-containing nanocomposites on the basis of epoxy diane resin (ED-20) by the methods of differential-thermal (DTA) and IR spectral (IRS), and X-ray diffraction (XRD) analyses has been investigated. It has been shown that introduction of metal-containing NF in composition with ED-20 shifts the cold curing reaction temperature from 90 to 75°C and hot curing from 125 to 100°C and favors increase in its thermal stability, which is confirmed by growth of activation energy of thermal-oxidative destruction (Ea) from 210 to 225 kJ/mol. It has been shown that the nanoparticles of copper oxide increase the thermal properties of ED-20 and are the catalysts of the curing reaction as evidenced by the height of the peak on the curing curve. In this case, the nanoparticles of zinc oxide hardly influence the thermal properties of nanocomposites on the basis of ED-20.
