Abstract

Porous silica/sodium polyacrylate nanocomposites were obtained in a one-stage sol-gel process. The process involved acid hydrolysis of tetramethoxysilane (TMOS) in the presence of sodium salt of poly(acrylic acid) (SPA) in the molar ratio of TMOS/SPA from 2:1 to 8:1. The physical and thermal properties of the obtained nanocomposites were characterized by FTIR, SEM, TGA and adsorption analysis (BET, BJH). The mechanical and chemical treatment of the composite after the synthesis increased its surface area without significantly changing its thermal properties. The process enables pore size control.

多孔聚丙烯酸钠/二氧化硅纳米复合材料的热性能

采用一步溶胶-凝胶法制备了多孔二氧化硅/聚丙烯酸钠纳米复合材料。该方法涉及在聚（丙烯酸）（SPA）钠盐存在下，以TMOS/SPA摩尔比为2:1至8:1对四甲氧基硅烷（TMOS）进行酸水解。通过FTIR、SEM、TGA和吸附分析（BET、BJH）对所获得的纳米复合材料的物理和热性能进行了表征。合成后对复合材料进行的机械和化学处理增加了其表面积，而没有显著改变其热性能。该工艺能够控制孔径。
