采用高内相比乳液模板法,以Span80为乳化剂,分别采用甲苯、氯苯、1,2-二氯苯、2-氯乙基苯、1-氯-3-苯基丙烷为非反应性溶剂制备了聚二乙烯基苯/苯乙烯多孔材料,分析了不同非反应性溶剂在多孔材料制备中对多孔材料表面形态和比表面积影响的作用机理。结果表明,非反应性溶剂的界面活性主要影响多孔材料的泡孔和窗口尺寸,而非反应性溶剂与聚二乙烯基苯/苯乙烯之间的相容性和非反应性溶剂的极性主要影响多孔材料的比表面积。
Using high internal comparison emulsion template method, using Span80 as emulsifier, toluene, chlorobenzene, 1,2-dichlorobenzene, 2-chloroethylbenzene and 1-chloro-3-phenylpropane were used as nonreactive Solvent Polyvinylidenebenzene / styrene porous materials were prepared, and the effect of different non-reactive solvents on the surface morphology and specific surface area of porous materials in porous materials was analyzed. The results show that the interfacial activity of the non-reactive solvent mainly affects the cell size and the window size of the porous material, while the compatibility of the non-reactive solvent with the polydivinylbenzene / styrene and the polarity of the non-reactive solvent are mainly Affect the specific surface area of porous materials.
