以苯乙烯(St)为单体,含甲基丙烯酰氧基丙基的有机硅树脂(MTQ)为交联剂,采用高内相比乳液模板(HIPE)法制备了蜂窝状、低密度及高孔隙率的MTQ/聚苯乙烯(PS)多孔复合材料,研究了MTQ对聚合物多孔复合材料微观结构、压缩性能及热稳定性的影响.结果表明:MTQ/PS多孔复合材料的泡孔呈立体球形且泡孔壁上有丰富的互连孔,相互贯通性良好,泡孔直径为2～9 μm,互连孔的孔径大小介于0.35～1.85 μm;所得多孔材料孔隙率可控,总孔隙率最高可达92％;该多孔复合材料的压缩强度为0.28～0.74 MPa,压缩模量为4.86～13.54 MPa.当MTQ与St的质量比为30∶100时,可获得泡孔直径较小、互连孔道较窄、压缩性能和热稳定性较好的MTQ/PS多孔复合材料.
