Fabrication of Surface Crosslinked Superabsorbent Polymers (SAPs) using Polycations |
| 초록 |
Superabsorbent polymer (SAP) is a hydrogel that can absorb and retain large volumes of water and aqueous solutions. SAP usually using in diapers, has requires various mechanical properties. Especially, due to the main characterization of the diaper, SAP needs to withstand high pressure and have high permeability to suppress the gel-blocking phenomenon. In our study, we fabricated the acrylic acid based spherical SAP through the Inverse-suspension polymerization of the partially neutralized acrylic acid monomers with internal crosslinkers. These manufactured spherical SAPs have high water retention capacity, but low elastic modulus and poor permeability. Therefore, we tried to surface crosslink using polycations on the spherical SAP particles to improve the mechanical properties and thus producing a core-shell structure. |
