Study on the nanocomposite material based on single-phase and two-phase mixtures of unsaturated polyesters with nanosilica.

Abstract

Nanocomposite material based on the single- and two-phase mixtures of unsaturated polyesters (orthophtalic 2211 N - orthophtalic HCP 110 and orthophtalic 2211N - isophtalic 2660) filled with nano SiO2 has been manufactured and studied. By the regulating phase structure and the choosing preferable filling phase it was possible to obtain an elastic module of 5 GPa after solidification of the polyesters mixture with the filling phase ofonly 1% nano SiO2, while for the case offilling nanosilica in the whole mixture volume this one was a little more than 3 GPo. It was shown that with the increase of nanosiliea concentration in the polyesters mixture the UV absorption (290 - 400 nm) of the nanosilicalpolyesters composite proportionally increased, while UV  transmission decreased respectively. but for the composite material filled with micro-sizedsilica this dependence did not appear.
