Abstract: Porous epoxy thermosets were prepared using poly(ethylene glycol) (PEG) as a template. The two epoxies that were used to make the porous thermosets were diglycidylether bisphenol-A (DGEBA), and triphenylolmethane triglycidyl ether (TGTPM). Trimethylolpropane tris(poly(propylene glycol)), amine terminated)ether (T-403) was used as a hardener in producing the thermosets. The porous thermosets were then characterized to determine their structural, thermal, optical, dielectric, and mechanical properties, and the results of these tests were compared to those for the bulk epoxy samples.
