Studies from Indian Institute of Technology in the Area of Nanocomposites Reported (Thermal stability and fire retardancy of polyurea and epoxy nanocomposites using organically modified magadiite)

By a News Reporter-Staff News Editor at Science Letter -- A new study on Nanocomposites is now available. According to news originating from Kharagpur, India, by NewsRx correspondents, research stated, "The purpose of this study is to investigate the effect of the surface modification of a layered silicate (magadiite) on the flammability of both polyurea and amine-cured epoxy resin. Based on the surface chemistry of magadiite, both quaternary alkyl ammonium and silane modifier can be employed for the organo-modification."

Our news journalists obtained a quote from the research from the Indian Institute of Technology, "Nanocomposites of both polymers were prepared via ultrasound-assisted in situ polymerization. Dispersion of magadiite was investigated through X-ray diffraction and high-resolution transmission electron microscopy. Thermal stability and flammability were evaluated by thermogravimetric analysis and cone calorimetry, respectively. The addition of small amount of magadiite resulted in significant improvements in flame resistance with not much change in thermal stability for both polymers."

According to the news editors, the research concluded: "Ammonium-modified magadiite improves the flame resistance, whereas silane modification helps to increase time to ignition of both polymers."
