Abstract
The effect of synthesized 5-((4-hydroxy-3,5-di-tert-butylphenyl)diazenyl)isophthalic acid (HBA) containing a hinderedphenol derivative on the thermooxidation, hydrochloric acid release time, and mechanical strength of PVC/CuO nanocompositeswas studied. Moreover, 5-((4-hydroxy-2,5-dimethylphenyl)diazenyl)isophthalic acid (HMA) was synthesized for comparison ofcorresponding PVC nanocomposite properties. PVC nanocomposite thin films were prepared through in situ surface modificationof CuO nanoparticles with HBA and HMA, individually, in the PVC solution. The XRD and FE-SEM results clarified the desirabledispersion of CuO nanoparticles. The PVC sample with loading of 5 wt% from each HBA and CuO was found to be the most thermallystable, which was confirmed by thermogravimetric analysis in inert conditions. The thermooxidation and Congo red test results revealedthat the simultaneous loading of HBA and CuO nanoparticles into the PVC matrix could increase the initial thermal degradation andthe stability times. Moreover, the PVC sample containing 2.5 wt% each from HBA and CuO nanoparticles exhibited tensile strengthalmost 20 MPa more than that of neat PVC.
