Abstract
|
The BCNswere chemicallymodified using acetic anhydride with the aimof improving its dispersion and interfacial adhesion. Acetylation of BCNswas confirmed by FT-IR spectroscopy. Morphology studies using TEMand SEM revealed that a reasonable dispersion of the modified BCNs in the EVA matrix was accomplished. The DSC data displayed a little shift in the Tg to higher temperatures with the incorporation of both modified and unmodified BCNs. Increased thermal stability of the nanocomposites consisting acetylated BCNswas confirmed by TGA technique. DMA measurements highlighted that the storage modulus increased and the damping properties decreased for the nanocomposites with regard to the neat EVA.
