Comparative investigations of radiation-grafted proton-exchange membranes prepared using single-step and conventional two-step radiation-induced grafting methods
(186–193)Polymer International 60 #2 (2011)
Nasef, Saidi and Dahlan of the Universiti Teknologi Malaysia, Malaysia prepared proton-exchange membranes containing poly(styrene sulfonic acid) grafts hosted in poly(vinylidene fluoride) (PVDF) films using two radiation-induced grafting methods: a single-step grafting method (SSGM) involving grafting of sodium styrene sulfonate onto electron beam (EB)-irradiated PVDF films and a conventional two-step grafting method (CTSGM) in which styrene monomer is grafted onto EB-irradiated PVDF films and subsequently sulfonated.  Membranes obtained using the SSGM were found to have superior properties compared to their counterparts prepared using the CTSGM process.  .(RDC 2/3/2011)
