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.
Claims16
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.
A process for manufacturing a porous epoxy membrane 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;
- placing the solution on a carrier;
- performing a first curing process to transform the reactant solution to a gel;
- and
- performing a second curing process to essentially remove all the remaining solvent and transform the gel to a porous epoxy membrane 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.
