Crystalline polymorph transition in poly(vinylidene fluoride) (PVDF)/acrylic rubber(ACM)/clay partially miscible hybrid

چکیده مقاله

This study investigates the intercalation of nanoclay in partially miscible blends of poly(vinylidene fluoride) (PVDF) and acrylic rubber(ACM). Transmission electron microscopy and X-ray diffraction technique were used to investigate the formation of nanoscale polymer blend/clay hybrids. Using Infrared spectroscopy and X-ray analysis, the different polymorph formation in PVDF nanocomposite and conjugated phases of partially miscible nanocomposite was studied. Nanoclay was found to induce b and c polymorphs while ACM tend to induce a phase in this polymer system. It was shown that PVDF chains in ACM-rich phase of partially miscible nanocomposites interact with ACM chains which in return form a polymorph in the presence of ACM. Further observations revealed that nanoclay in a polymorph is wrapped by ACM molecules. Keywords Nanocomposite Partial miscibility
