B. Gupta et Gg. Scherer, PROTON-EXCHANGE MEMBRANES BY RADIATION-INDUCED GRAFT-COPOLYMERIZATIONOF MONOMERS INTO TEFLON-FEP FILMS, Chimia, 48(5), 1994, pp. 127-137
A state-of-the-art in radiation-induced graft copolymerization of styr
ene and acrylic acid monomers into Teflon-FEP films is presented with
a view to develop proton exchange membranes for various applications.
This process offers an easy control over the composition of a membrane
by careful variation in radiation dose, dose rate, monomer concentrat
ion, and temperature of the grafting reaction. By varying the nature a
nd the amount of the grafted content, it is possible to achieve a memb
rane with desired physico-chemical properties. In this paper, a correl
ation among the degree of grafting, structural changes, and properties
of graft copolymer membranes is discussed.
