Abstract
Cotton grafted with acrylamide (cellulose-g-polyacrylamide) was prepar ed by using ceric ion as initiator. The dielectric properties of graft ed cotton were studied. Also, the effect of the grafting percentage on these properties was discussed. The results indicate that the dielect ric constant, epsilon', decreases as the percentage of grafting increa ses, which may be due to the reduction in the number of the polarized groups (OH groups) of cellulose, due to grafting.
