摘要

In the proposed research article, polymer nanocomposites on the basis of thermoset polymer resultant blends (epoxy/polyester) having wollastonite powder are prepared by high shear mixer (mechanical), followed by an ultra-sonicator for uniform dispersion of wollastonite particulates in the final blend matrix. Wide range percentages of modified wollastonite nano-particulates with 0, 1, 2, 3, 4 and 5 wt. % were incorporated into the epoxy/polyester blend matrix in order to evaluate the effect of nanofillers on nanophase morphological structure and to study material properties. Various thermal parameters of the nanocomposite were evaluated using thermogravimetric analysis and differential scanning calorimetry techniques. Further, the scanning electron microscopy images have been employed to know fractured surfaces of the titled compound. From the experimental data it was found that uniform miscibility of epoxy/polyester blend mix and homogenous dispersion of wollastonite nano particulates in the blend matrix was noticed. From the TGA studies, 8 % weight loss and 4 °C rise in decomposition temperature was observed with addition of 5 wt. % wollastonite when compared with the 0 wt. % wollastonite combination of epoxy/unsaturated polyester resin blend. DSC results further revealed that the modified wollastonite nanoparticles is major responsible for the glass transition temperature (Tg) of the nanocomposites.
