Repurposing Waste Sulfur for the Ionic Vulcanization of Nanocellulose Hydrogels
Small Methods, Volume 9, Issue 12, December 1, 2025.Herein the ionic crosslinking of cellulose nanocrystals using sodium polysulfides is demonstrated. Chain entanglement, derived from O‐Ca‐S bridges within a hydrogel structure forms hydrophobic occlusions, leading to a significant increase in the material storage modulus and the swelling potential, thus translating to a potential application in ...
