摘要

The present paper comprises of hydrogel synthesis processes using a blend of three natural polysaccharides (PsB) "starch, chitosan and alginate" grafted acrylamide (PsB-g-Am) using ultraviolet (UV) irradiation. The grafting process has been undergo using three different photo-initiators [Dimethoxy-2-phenylacetophenone (DMPA), benzoin methyl ether (BME) and benzophenone (BP)]. Furthermore, different PsB/Am weight ratios have been used. The prepared hydrogel has been characterized using XRD and SEM. Grafting percentage (%G), grafting efficiency (%GE), grafting yield (%GY) also have been compared. Among the three used photo-initiators, DMPA gave the maximum attained values of %G (130 %), %GE (72 %) and %GY (89 %) followed by BME and BP, respectively. Swelling water ratio (SWR) for the grafted hydrogels in distilled water (DW) has been studied. Grafted hydrogel using DMPA photo-initiator gave the maximum SWR of 30 g/g. Am/PsB weight ratio and the used photo-initiator had a direct effect on SWR of the produced hydrogel.
