Abstract
— In this work, cation exchange membrane is developed
using simultaneous radiation induced grafting technique.
Grafting of styrene monomer has been done on polyethylene
coated polypropylene fabric (PPF) using different absorbed doses
upto maximum of 10 kGy. The sulphonation of styrene grafted
PPF has been done by refluxing it in sulphuric acid. Fourier
transform infrared spectroscopy (FTIR) has confirmed the
grafting of styrene on PPF and the intensity of the phenyl groups
is dependent on the amount of absorbed dose. X-ray diffraction
(XRD) analysis revealed a decrease in crystallinity of grafted PPF
and its sulphonated form. Thermal analysis (TGA) showed
marked decrease in the thermal stability of sulphonated PPF as
compared to styrene grafted PPF. Scanning electron microscopy
(SEM) showed an increase in the thickness of fiber after grafting
and sulphonation. In addition, the smooth surface of the fabric is
changed into rough surface in sulphonated PPF. The PPF has
shown 205.4 % grafting of styrene at 10 kGy and its sulphonated
form have an ion exchange capacity value of 3.66 meq/g.
