The changes of absorption behaviors in superabsorbent copolymers using polycation salts |
| 초록 |
SAP has a 3D poly network structure and expands in the process of absorbing water. We copolymerized itaconic acid (IA), vinyl sulfonic acid, and tetra(ethylene glycol) diacrylate to prepare SAP. IA based SAP has lower absorbency under load (AUL) than conventional acrylic acid based SAP. To solve this problem, we added polycationic salts when synthesizing SAP. Among the various polycationic salts, aluminum sulfate and zirconium sulfate were used. We analyzed SAP structure and compared the absorption characteristics of IA based SAPs according to the addition polycation salts. The structure of SAP was characterized by FT-IR. XPS analysis confirmed the presence of polycation salts in the SAP. The absorption performance of SAP were evaluated by measuring centrifuge retention capacity and AUL. |
