Approaches to Enhance Mechanical Properties and Proton Conductivity of Nanocomposites by in-situ Bonding

摘要

Increasing demand for special materials has led to the conception of composites,since valuable properties of different types of materials can be combined.In-situ nanocomposition is an ideal technique to make a perfect dispersion of nano materials into polymer matrixes and improve thermal,electrical and mechanical properties of polymers.In our studies,biodegradable poly (butylene succinate) (PBS)/single-walled carbon nanotube (SWCNT) nanocomposites were successfully prepared through covalent bonding between PBS and acyl aminopropyltriethoxysilane functionalized SWCNT (SWCNT-APTES).Covalent bonding after hydrolysis forced SWCNT with better dispersion in the PBS matrix and nanocomposites with higher tensile strength and less loss tanδ.
