Properties of superabsorbent polymers using biomass based crosslinker |
| 초록 |
Superabsorbent polymers (SAPs) are special polymeric materials that can absorb large amounts of water, saline solutions or physiological fluids in their structure. In this study, we synthesized copolymers using carboxylized acrylic monomer and vinyl sulfonic acid. Each monomer was neutralized with sodium hydroxide in order to improve the absorption performances such as centrifuge retention capacity and absorbency under load. We initiated polymerization with ammonium persulfate after the input of the crosslinker. We prepared the SAPs with biomass-based crosslinker according the content or non-biomass based crosslinker. We confirmed the structure of SAPs using FT-IR spectroscopy and evaluated the absorption properties in 0.9 wt. % saline solution. As a result, the performance of SAP using biomass based crosslinker was similar to that of SAP using non-biomass based crosslinker. |
