摘要
以丙烯酸丁酯和丙烯酸异辛酯为单体,分别以二甲基丙烯酸乙二醇酯(EGDMA)、二乙烯基苯(DVB)为交联剂,采用高内相比乳液模板法制备了聚丙烯酸酯W/O型的乳液,所得乳液经固化得多孔材料。通过SEM、UV-Vis、TGA等表征手段讨论了两种交联剂对聚合物多孔材料的结构与性能的影响。结果表明:使用DVB作为交联剂的多孔材料泡孔排布更加紧密有序且孔径较小,对罗丹明B水溶液的吸附性能相对较高,其多孔材料的耐热温度高了60℃左右。
The polyacrylate W/O emulsion was synthesized by hlgla internal plaanse emulsion （HIPE） template using butyl acrylate, 2-ethylhexyl acrylate as the monomers, and ethyleneglycol dimethacrylate （EGDMA）, divinylbenzene（DVB） as the cross-linking agents respectively. And the porous polymer materials were obtained after curing. The influence of EGDMA or DVB as the cross-linking agent on the morphology and the thermodynamics of the porous polymer materials were analyzed through scanning electron microscopy, UV-Vis spectrophotometer, and thermo-gravimetric analysis. The results showed that the voids of porous polymer materials were more orderly and closed using DVB as the cross linking agents, and the adsorption effect of Rhodamine B was better, and the decomposition temperature increased about 60℃.
