Synthesis, Characterization and Thermal Properties of Polyurethane-Urea Nanocomposite with Nanodiamond
Author(s):
Abstract:
Polyurethanes due to their excellent properties are used in different industrial applications. Polyurethane and polyurethane-ureas have been used as coating materials in factories ground areas and sport fields during the last decades. But improving their thermal stability was always the major goal for developing their applications. In this study the polyurethane-urea nanocomposites with nanodiamond were prepared by in situ polymerization and their chemical structure, thermal stability, glass transition temperature and also crystallinity were measured. The results showed 13˚C improvement in thermal stability by using only 0.1% of nanodiamond in polymer matrix. Glass transition temperature (Tg) was also increased and soft segment crystallinity was decreased by addition of nanodiamond in polymer matrix.
