4-Styrenesulfonyl chloride was synthesized successfully and characterized by FTIR
1H NMR and 13C NMR spectra. Quantum chemistry calculation based on density functional theory was carried out for this synthesized monomer
and the Mulliken population analysis showed that 4-styrenesulfonyl chloride possess comparative charge distribution to styrene
which is commonly used as graft monomer in the preparation of proton exchange membrane
indicating that 4-styrenesulfonyl chloride is possible to be used as graft monomer. Fukui function of 4-styrenesulfonyl chloride declared that the alpha carbon of the vinyl is susceptible to electrophilic attack while the beta carbon showed higher reactivity with respect to nucleophilic and radical attack. Radiation induced graft polymerization of 4-styrenesulfonyl chloride on to FEP film was taken under 60Co gamma rays. After hydrolysis with KOH
H2SO4 solution and rinsing by deionized water to neutral
the membrane turned into proton conductive. The conductivities of these membrane are in accordance with the graft yield and increase with temperature. Conductivity of the membrane with does rate of 20 Gy·min-1 reached 84.56 m S·cm-1 at 348 K.
