Abstract
Polymeric materials and their composites have attracted great attention because of their great significance. This study includes preparation of composites of carbon nano-particles/Polypyrrole (CB/PPY) embedded in Ethylene-vinyl acetate copolymer (EVA) with different contents as 0, 5, 10, 15, 20 and 30 parts per hundred parts by weight of polymer (pph). X-ray diffraction (XRD) was investigated to characterize the structure of the prepared composites. Thermal analysis including differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were measured to detect the miscibility degree of the composites and their thermal stability, respectively. The Gordon – Taylor equation was modified to fit the experimental values of the glass transition temperatures (Tg) at low and high contents of CB/PPY. The obtained values of Tg showed complete miscibility of most of the composites. From XRD measurements, the crystallinity of the composites was found to be decreased by embedding (CB/PPY) into EVA. The curves of TGA show more thermal stabilities for the composites compared to the pristine EVA.
