Abstract:
1. A process for manufacturing a porous epoxy network with open pores comprising the steps of: providing a reactant solution comprising an epoxy resin, a solvent selected from n-hexane, cyclohexane, cyclohexanol, diisobutyl ketone, isopropanol, benzene, toluene, tetrahydrofuran, chloroform, methyl cyclohexane, dipropyl ether, methyl isobutanone, butyl butanoate, ethyl butanoate, and a combination thereof and a curing agent; performing a first curing process to transform the reactant solution to a gel; and performing a second curing process to essentially remove the remaining solvent and transform the gel to form a porous epoxy network with open pores; wherein the curing agent is a tertiary amine selected from the group consisting of 2,4,6-tris(dimethylamino methyl)phenol, 2-(diemthylamino methyl)phenol, α-methyl benzyl dimethyl amine, 2-dimethyl amino-2-hydroxy propane, triethanol amine, dialkyl amino ethanol, N,N′-dimethyl piperazine and a combination thereof.
