Stabilization study of P hotodegra dation of acrylonitrile–butadiene–sty rene (ABS )/TiO۲ po lymeric nanocomp osite

the photodegradation of acrylonitrile–butadiene–styrene ( ABS)/TiO۲ nanocom posite investigated under exposure to UV lig ht (۹۰W) in weathering chamber. Stabilizatio n was monitored in term s of chang es at four v arious times by using of Fourier Tr ansform In frared Spectroscopy (FT -IR), X-ra y diffractio n (XRD) patterns, Sca nning Electron Microscopy (SEM) and Differential Scan ning Calorim etry (DSC) were also used to assess the stability of nanocomposite. The results su ggest that a better perfo rmance was achieved f or stabilized ABS sample with TiO۲ nanoparticles, which a re very im portant to e xtend the co polymer lifetime and significantly reduce the rate of degradation of po lymer and providing a protective barrier to nanocomposite
