The effects of initiator content on sago (metroxylon rottb.) starch-G-PAN hydrogel

This paper explores the effects of ammonium persulphate (S-PANHs) content (1wt % - 5 wt %) to the properties of sago starch-graft-polyacrylonitrile hydrogels (S-PANH). S-PANHs were prepared via graft copolymerization of polyacrylonitrile (PAN) onto sago starch in the presence of ammonium persulphat...
