Synthesis of pH-Sensitive Hydrogel Based on Starch-Polyacrylate Superabsorbent
In this article, we synthesize of a novel starch-based superabsorbent hydrogel via graft copolymerization of mixtures of acrylic acid (AA) and 2-Hydroxy ethyl methacrylate (HEMA) onto starch backbones. The polymerization reaction was carried out in an aqueous medium and in the presence of ammonium persulfate (APS) as an initiator and N,N’-methylene bisacrylamide (MBA) as a crosslinker. The hydr...
متن کاملSYNTHESIS AND SWELLING BEHAVIOUR OF COLLAGEN-g-POLY(MAA)/KAOLIN SUPERABSORBENT HYDROGEL COMPOSITES
In this work, a novel superabsorbent hydrogel composite based on collagen have been prepared via graft copolymerization of methacrylic acid (MAA) in the presence of kaolin powder by using methylenebisacrylamide (MBA) as a crosslinking agent and ammonium persulphate (APS) as an initiator. A proposed mechanism for hydrogel formation was suggested and the structure of the composite was established...
متن کاملSynthesis and Swelling Behavior of Carrageenans-Graft-Poly(Sodium Acrylate)/Kaolin Superabsorbent Hydrogel Composites
In the present paper, a novel superabsorbent hydrogel composite based on carrageenan have been prepared via graft copolymerization of acrylic acid (AA) in the presence of kaolin powder using methylenebisacrylamide (MBA) as a crosslinking agent and ammonium persulfate (APS) as an initiator. The certain variables of the graft copolymerization (i.e. the monomer, the initiator and the crosslinker c...
متن کاملdewatering of yoghurt using permeable membrane and acrylic superabsorbent hydrogel
conventional processes of food dewatering, such as thermal, have undesirable and destruction effects on vitamins, aromatic compounds and pigments. in addition, they are accompanied with some technological complications and energy consumption. thus, food concentration processes are directed to non-thermal techniques or methods with reduced heat effects. superabsorbents are highly hydrophilic pol...
متن کاملPreparation and Characteristics of Corn Straw-Co-AMPS-Co-AA Superabsorbent Hydrogel
In this study, the corn straw after removing the lignin was grafted with 2-acrylamido-2-methylpropanesulfonic acid (AMPS) to prepare sulfonated cellulose. The grafting copolymerization between the sulfonated cellulose and acrylic acid (AA) was performed using potassium persulfate and N,N1-methylenebisacrylamide as the initiator and crosslinking agent, respectively, to prepare corn straw-co-AMPS...
