Microstructural and thermal investigations of carbon nanotube additive Se80Te16Cu4 glassy composites

Carbon nanotube (CNT) additive Se80Te15Cu4 glassy composites were prepared by melt-quenching technique. The structural, microstructural, and thermal characterizations were performed by x-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive x-ray analysis (EDAX), and differential scanning calorimetric (DSC) technique. Microstructural study of CNT additive Se80Te16Cu4 glassy composites showed the inorganically filled CNT tubular morphology which was observed for the first time. In addition, the glass transition temperature (T-g) and crystallization temperature (T-c) of CNT additive Se80Te16Cu4 glassy composites exhibited remarkable variation due to CNT incorporation which can be explained on the basis of CNT mediating through crosslink with the glassy matrix.
