Thermal conductivity and thermal properties of POSS/ polytriazole organic- inorganic hybrid material

摘要

To decrease the thermal conductivity of polytriazole-based fiber reinforced composites, an organic-inorganic POSS/polytriazole hybrid resin was obtained. The influences of various proportions of POSS on thermal conductivity and the thermal properties of hybrid materials were emphatically investigated. The results show that POSS incorporation resulted in not only decreased thermal conductivity but also increased T-g and thermal decomposition temperature. The enhancement was ascribed to the nanoscale effect of POSS structure and the fact that the POSS framework has a high heat resistance property. (c) 2015 Wiley Periodicals, Inc. J. Appl. Polym.
