Abstract

A method of forming a high internal phase emulsion (HIPE) foam is provided. A nitroxide-containing monomer can be used in combination with other monomers that can then be used to make a high internal phase emulsion foam upon curing. The nitroxide group can subsequently be used to control the radical polymerization of many monomers, which can be grafted from the surface of the high internal phase emulsion foam. The resulting foam can be useful in performing separations of radioactive species, metals, metal ions, multi-element ions, metal complexes, halides, and organic chemical species in chemical process streams, clean-up operations, etc.
