Impact of Crosslinking Degree on Epoxy Membrane Performance

Epoxy membranes with different crosslinking degrees were prepared and characterized to investigatethe effect of curing degree on membrane performance. The pure water flux (PWF) test determinedthat higher curing degrees measured with differential scanning calorimetry (DSC), led to a higherpermeation pressure (PP) while maintaining the same PWF. Field emission scanning electronmicroscope (FESEM) images showed a sponge-like morphology where increasing the crosslinkingdegree led to higher mean pore size in membrane cross-section. The swelling test indicated thatincreasing the crosslinking degree led to lower stability towards organic solvents.
