Thermal properties of porous sodium polyacrylate/silica nanocomposites
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.
