Research Abstract

Light-transmitting, low-density organic-inorganic hybrid solid materials suitable for heat-insulation were obtained in the methylsilsesquioxane system via one-step synthesis using surfactants and urea as additives followed by either super-critical or ambient evaporation drying of the solvent. Gels with hierarchiall macro-and mesopores have also been synthesized by careful tuning ofthe compositions and reaction conditions. The relation between gas pressure and thermal conductivity of the above materials have been investigated in relation to their pore structures.
