Studing the factors which affect on the chemical structures- morohology and thermal stability of polythiophene and composites

The current research contains 2 parts: The first part is related to, polythiophene /aluminum oxide (PTh/Al2O3) nanocomposite which Was prepared in the aqueous media using PVA as a surfactant. morphology, thermal stability and thermal degradation were studied by scanning electron microscopy (SEM), X-ray diffraction (XRD), thermal gravimetric analysis (TGA). The second part studied, PVC particles were coated with PTh , by using chemical oxidative polymerization method. The chemical structure, morphology were studied by fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM). The results indicate that Al2 O3 and PVA affect on the properties of composites. Also, he PTh can be uniformly coated on the surface of PVC particles by chemical oxidative polymerization.Scanning electron microscopy ( SEM) , Fourier transforminfrared ( FTIR) proved that PVC influence the properties of product.
