A novel two-step process for porous melamine-formaldehyde polymer (MF) with high surface area was developed. Curing of MF polymer in aprotic solvent (e.g. dimethyl sulfoxide) produced a porous structure by eliminating small molecules as a by-product. MF polymers with a various shape such as particles or rods, transformed to the porous polymers while maintaining their shapes though the curing process. The porous MF polymers have been characterized by optical microscopy (OM), scanning electron microscopy (SEM), and N2 adsorption. These porous MF polymers could be utilized in CO2 or metal ion capture with the abundant nitrogen functional groups and high surface area.
