Project Details


Due to their potential in exhibiting tailored and functional properties, polymer blend-based nanocomposites have been attracting much attention in the past decade. In the immiscible blend-based nanocomposites, the nanofiller(s) could exhibit “(double) percolation” phenomenon and/or played as a compatibilizer to enhance the properties of the blends. Hitherto, most of the studies are concerned of the blend-based ternary nanocomposites with one filler addition. The investigation on the hybrid fillers-added composites is limited. From academic and practical viewpoints, the four-component nanocomposite systems merit investigation to extend the applications of various immiscible blends. To control the final properties of the multi-component system, the “mixing” condition (parameters) plays an important role, indeed. Polyamide 46 (PA 46) offers attractive properties in its super thermal resistance and high stiffness. Poly(vinylidene fluoride) (PVDF) shows remarkable chemical, mechanical and electrical properties. In spite of possessing many unexcelled properties, PA 46 and PVDF show some disadvantages upon certain applications. In this 2-year project, the PA 46/PVDF blend-based four-component nanocomposites will be prepared through different melt-mixing procedures. The relation between the phase morphology/structure and properties of the composites will be explored. The hybrid nanofillers, organoclay/MWNT and organoclay/GNP, will be incorporated into the blend matrix sequentially.and/or simultaneously. Special attentions will pay to the crystal form of PA 46/PVDF, compatibilizer role of nanofillers, and the forming mechanism of (double) percolation. *MWNT: multi-walled carbon nanotube; GNP: graphene nanoplatelet
