A hierarchical porous structures of melamine-formaldehyde resin that contains meso and macro pores with high surface area has been synthesized via high internal phase emulsion (HIPE) polymerization and solvent-assisted curing. High internal phase emulsion polymerization, a convenient synthetic pathway with 3 components, aqueous phase, oil phase and stabilizer, was used to make macroporous melamine- formaldehyde resin (polyHIPE). Solvent-assisted curing of the polymer created a mesoporous structure in the skeletal framework of maroporous melamine-formaldehyde resin. The meso and macro porous melamine-formaldehyde resin was characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), Hg porosimetry, N2 sorption isotherm and Brunauer-Emmett-Teller (BET) analysis. |
