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.

在甲基倍半硅氧烷体系中，以表面活性剂和尿素为添加剂，通过一步合成，然后对溶剂进行超临界干燥或常压干燥，得到了适合隔热的透光、低密度有机-无机杂化固体材料。通过仔细调整组成和反应条件，还合成了具有分级大孔和中孔的凝胶。研究了上述材料的气体压力与导热系数之间的关系及其与孔结构的关系。
