Article Synopsis
- Carboxylated nanocellulose superabsorbents (SAPs) can be created by modifying cellulose fibers with different cations, affecting their gel structure and properties.
- Seven cations of varying valencies were tested for their influence on the gelation process and superabsorbent performance, showing that the type of counter-ion significantly impacts absorption capacity in deionised water.
- The stability and performance of these gels depend on the cation's valency, with monovalent cations relying on physical interactions for gelation and divalent cations creating stronger ionic cross-links, leading to differences in absorption rates.
