A novel ultraviolet (UV) cross-linking method using fluorine-containing telechelic polyimide membranes was investigated. The base fluorine-containing polyimide was synthesized by polycondensation using the monomers, 4,4′-(hexafluoroisopropylidene) diphthalic anhydride (6FDA) and 2,3,5,6-tetramethyl-1,4-phenylene diamine (TeMPD). Both chain ends of the 6FDA-TeMPD polyimide were end-capped with either UV-reacted groups, 1,1-bis(acryloyloxy methyl) ethyl isocyanate (BEI) group or p-aminostyrene (PAS) group. The two types of telechelic polyimide membranes, 6FDA-TeMPD-BEI and 6FDA-TeMPD-PAS, were formed with UV irradiation from the low-viscosity solutions using the solvent-casting method.
