高内相乳液模板法制备聚合物多孔材料研究进展

Progress of Porous Polymeric Materials Preparation via High Internal Phase Emulsions Template Method

聚合物多孔材料因具有高孔隙率、低密度、比表面积大等特点受到了人们的广泛关注,而目前聚合物多孔材料大多以高内相乳液模板法来制备,文中主要针对高内相乳液模板法所用乳化剂,分别介绍了小分子乳化剂、固体乳化剂、嵌段共聚物乳化剂对制备的聚合物多孔材料孔结构的影响,并简要介绍了以高内相乳液为模板制备的聚合物多孔材料在吸附、催化等领域的应用。

Porous polymer materials have interests of attracted scientists for a long time, due to its high porosity, low foam density and high specific surface area properties. Currently, porous polymer materials were prepared by high internal phase emulsion templates. This article introduced the surfactants for stabilizing high internal phase emulsion templates, such as low molecular weight surfactants, solid particle surfactants and block copolymer surfactants. The influence of surfactants on the structure of porous polymer materials was discussed. Besides, the porous polymers materials prepared by high internal phase emulsion templates played an important role in the field of catalyst, adsorbent and so on.
