Indian Institute of Technology Reports Findings in Nanocomposites [Facile preparation of highly exfoliated and optically transparent polycarbonate (PC)/clay mineral nanocomposites using phosphonium modified organoclay mineral]

By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Nanocomposites are presented in a new report. According to news originating from Kharagpur, India, by NewsRx correspondents, research stated, "Here, we focus on the morphology, mechanical and optical properties of the polycarbonate (PC) in the PC/clay mineral nanocomposites prepared through both the melt and solution blending technique at two different loadings (0.5 phr and 1 phr) of propyl triphenyl phosphonium modified montmorillonite (PTPP-Mt). The modified organo-Mt was prepared by ion exchange reaction and verified through FOR spectroscopy, EDS study and XRD analysis."

Our news journalists obtained a quote from the research from the Indian Institute of Technology, "The outstanding thermal stability of the PTPP-Mt at the processing temperature of PC (280 degrees C) made it a suitable candidate for the preparation of optically transparent PC/Mt nanocomposites. The XRD analysis over the PC/PTPP-Mt nanocomposites revealed the destruction of ordered geometry of the clay mineral, whereas, the presence of some localised zones of Mt was evident from transmission electron microscopic (TEM) analysis. Thermal analysis indicated an increase in glass transition temperature (T-g) and thermal stability of PC in the nanocomposites. The strength and modulus of the nanocomposites were increased with increase in Mt loadings. An increase in storage modulus in the nanocomposites was evident from the thermomechanical studies."

According to the news editors, the research concluded: "Finally, the optical transparency of PC was retained without generation of any colour in the PC/PTPP-Mt nanocomposites."
