The microstructures of the porous polymers and crosslinked porous polymers were observed by scanning electron microscopy. The adsorption capacities of the polymers toward methanol, dichloromethane, acetone, tetrahydrofuran, toluene, hexane, and kerosene were assessed and rationalized in terms of the surface microstructures of the polymers. The time courses of the adsorptions were investigated, revealing a two-step adsorption process comprising rapid permeation into the cavities of the porous polymers followed by a slow swelling step.

使用低分子量凝胶剂制备的凝胶乳液及其在多孔聚合物合成中的应用

摘要 以N-3-羟丙基羰基-L-异亮氨酰-氨基十八烷为凝胶剂，成功制备了由水和单体组成的油包水（W/O）凝胶乳液。用氧化还原引发剂对凝胶乳液进行低温聚合以获得相应的多孔聚合物。此外，含有双官能单体的凝胶乳液聚合得到交联的多孔 PMMA-HDODA、PMMA-EGDMA、PMMA-DVB 和 PSt-DVB，它们被发现具有机械强度和耐溶剂性。通过扫描电子显微镜观察多孔聚合物和交联多孔聚合物的微观结构。聚合物对甲醇、二氯甲烷、丙酮、四氢呋喃、甲苯、己烷、根据聚合物的表面微结构对煤油和煤油进行了评估和合理化。研究了吸附的时间过程，揭示了两步吸附过程，包括快速渗透到多孔聚合物的空腔中，然后是缓慢的溶胀步骤。通过接触角测量证实了交联多孔聚合物的高防水性。通过反复吸附和干燥评估聚合物作为溶剂吸收剂的可重复使用性。 使用 N-3-羟丙基羰基-L-异亮氨酰-氨基十八烷成功制备了由水和单体组成的油包水 (W/O) 凝胶乳液作为凝胶剂。用氧化还原引发剂对凝胶乳液进行低温聚合以获得相应的多孔聚合物。含有双官能单体的凝胶乳液聚合得到交联的多孔聚合物，发现其具有机械强度和耐溶剂性。聚合物对几种液体的吸附能力根据聚合物的表面微结构进行了评估和合理化。研究了吸附的时间过程，揭示了两步吸附过程，包括快速渗透到多孔聚合物的空腔中，然后是缓慢的溶胀步骤。
