Effect of multivalent cation substitution on the surface-crosslinking of the superabsorbent polymer |
| 초록 |
The superabsorbent polymer (SAP) is a crosslinked hydrophilic polymer capable of absorbing tens or even thousands of times its own weight of water. The SAP swelled in the fluid exhibits a gel blocking phenomenon which interferes with the flow of the fluid due to the adhesion phenomenon between the particles. We synthesized the core-SAP by the copolymerization of the carboxylized acrylic monomer and vinyl sulfonic acid, and surface-crosslinked it to alleviate the gel blocking phenomenon. In order to control the surface-crosslinking density of the SAP, surface-crosslinking medium solution containing aluminum sulfate and zirconium sulfate, which are water-soluble salts containing multivalent cations, was used. The structure of the SAP was confirmed by FT-IR. We measured centrifuge retention capacity, absorbency under load, and the liquid permeability of the SAP. We also investigated the surface of the SAP by SEM. |
