  • Process for manufacturing porous epoxy with open pores and porous epoxy made therefrom
    Patent number: 8410186
    Abstract: The present invention relates to a process for manufacturing a porous epoxy network, especially a porous epoxy membrane. The process according the present invention comprises the steps of: providing a reactant solution comprising an epoxy resin, a solvent 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.
