Preparation of Porous Polymers by 'in Situ Precipitation' Using Low Molecular Weight Gelators

摘要

Highly porous polymer and inorganic materials with a well-defined pore size have been exploited in a wide range of applications such as chemical catalysis, ionic exchange resins, chemical sensors, and functional materials for selective binding and removl of drugs, peptide, and proteins.~1,2 The template-imprinting technique is very useful method in the preparation of these materials with size-and shape-specific binding sites. Often porous polymers have been prepared using reversible micelles as the templates,~3 especially sodium bis(2-ethylhexyl) sulfosuccinate (AOT) in the mixture of water and many organic solvents,~4 because the size of the micelles can be controlled by changing the water content.~3a,3b
