摘要:
以乙烯基三乙氧基硅烷为原料,采用溶胶-凝胶法制备粒径均一的乙烯基SiO2杂化硅球(Vinyl-SiO2),并与丙烯酰胺、阳离子单体发生原位聚合,成功制备出树枝状SiO2/CPAM无机-有机杂化材料。通过扫描电镜和透射电镜表征杂化材料的微观形态结构; 热重分析证实其多级分解,差示扫描量热仪测定出玻璃化转变温度为167.06℃。通过对杂化材料的特性黏数和Ca2+吸附量分析,得出以下优化条件:当Vinyl-SiO2用量为0.5%,阳离子单体用量为17.5%以及引发剂用量为0.6%时,SiO2/CPAM的特性黏数为159.2 mL·g-1,Ca2+吸附量为4.3 mmol·g-1。
Abstract:
Dendritic inorganic-organic hybrid materials silica/cationic polyacrylamide(SiO2/CAPM)were successfully prepared by in-situ polymerization using acrylamide, cationic monomer and hybrid silica spheres containing vinyl group with a uniform size, which were synthesized using vinyltriethoxysilane via sol-gel process. The micromorphology and structure of SiO2/CAPM were characterized by scanning electron microscopy(SEM)and transmission electron microscopy(TEM); multistage decomposition was confirmed by thermogravimetry, and the glass transition temperature of 167.06℃ was determined by differential scanning calorimetry. Based on the analysis of intrinsic viscosity and adsorption amount of Ca2+ of SiO2/CAPM, the following optimization conditions were obtained: the intrinsic viscosity of SiO2/CAPM was 159.2 mL·g-1 and the adsorption amount of Ca2+ was 4.3 mmol·g-1, when the dosage of Vinyl-SiO2, cationic monomer and the initiator was 0.5%, 17.5% and 0.6%, respectively.
