Synthesis and Characterization of Starch-Based Superabsorbent Polymers Grafted with Itaconic Acid and Organo-modified Montmorillonite |
| 초록 |
Superabsorbent polymer (SAP) is a functional polymer that absorbs and retains more than 100 times the weight of the sample. Acrylic acid (AA), which is widely used as a material for SAP, is excellent in absorption rate, but does not biodegrade and causes environmental pollution. In this study, starch and itaconic acid (IA) were copolymerized to produce environmentally friendly SAP. Starch is a natural polymer in which α-glucose monomers are polymerized by α-1,4 glycosidic bonds. It is abundant in nature and shows biodegradability. IA has a double-bond similar to AA, which is grafted with hydroxyl group of starch to form ether group. Organo-modified montmorillonite (OMMT), a nanoclay, was added between the networks formed by starch-graft-IA to produce a SAP that absorbed a large amount of water. The results of this study were obtained by measuring the free-swelling in DI water and absorption capacity in 0.9 wt% NaCl solution, and analyzed structures by FT-IR and XPS. |
