本论文采用细乳液模板法制备了具有连通结构的多孔聚合物整体材料。实现了具有亚微米孔结构的多孔整体材料的制备，并显示出制备具有互连结构的纳米多孔整体材料的巨大潜力。以中等内相细乳液为模板制备了具有开孔结构的聚合物整体柱。孔隙率降低到47%，这增加了多孔单块的机械强度超过40倍，与传统的高内相乳液聚合方法相比。
In this work, a miniemulsion template method was proposed to prepare a porous polymeric monolith with an inter-connected structure. The preparation of a porous monolith with sub-micrometer pore structure was realized and showed great potential to prepare a nanoscale porous monolith with an inter-connected structure. A medium internal phase miniemulsion was employed as a template to prepare the polymeric monolith with an open-cellular structure. The porosity was decreased to 47%, which increased the mechanical strength of the porous monolith more than 40 times compared with those prepared from conventional high internal phase emulsion polymerization methods.
