为了获得性能优异的聚合物多孔材料,首先,在封端剂六甲基二硅氧烷(MM)的存在下,通过硅酸钠与甲基丙烯酰氧基丙基三甲氧基硅烷(MPS)的水解缩聚反应制备了含甲基丙烯酰氧基丙基官能基团的MTQ有机硅树脂;然后,以MTQ硅树脂为交联剂,丙烯酸异辛酯(EHA)为单体,利用高内相比乳液模板法制备了MTQ硅树脂/聚丙烯酸异辛酯(PEHA)聚合物多孔材料;最后,对该多孔材料的孔结构、压缩性能和热稳定性进行了研究.结果表明:采用MTQ硅树脂作为交联剂制备得到的MTQ硅树脂/PEHA聚合物多孔材料的泡孔孔径介于4～10μm范围内,毛孔孔径分布于0.3～2.0 μm区间内;泡孔之间紧密相连,毛孔均匀分布且通道较窄.MTQ硅树脂含量对MTQ硅树脂/PEHA聚合物多孔材料的比表面积和孔容的影响较小,但可显著提高聚合物多孔材料的热稳定性和压缩强度;在氮气氛围下,聚合物多孔材料的最大热分解速率温度可达411.5℃.
