Abstract

In this article, the chemistry of interfacial adhesion between different additive systems has been dealt with to develop a high performance nanocomposite and in the process, a comprehensive study on the reinforcing effect of nanosilica has been carried out. The base polymer was considered as the blends of Poly ethersulfone (PES) and thermotropic liquid crystalline polymer (TLCP). A novel polymeric compatibilizer, polyphosphazene elastomer, has been utilized and the interchain crosslinking has been explained. Results of experimental investigations demonstrate that the nanofillers play an important role in reducing the interfacial tension. However, the presence of Polyphosphazene elastomer, acted as compatibilizer further reducing the interfacial tension through the inter‐molecular interaction. The nanocomposites, thus developed, have better thermal stability and improved rheological properties. In addition, it has also been observed that Polyphosphazene elastomer impart flexibility in the composite. POLYM. COMPOS., 2010. © 2009 Society of Plastics Engineers
