摘要: Abstract Photocrosslinkable hydrogels composed of natural materials exhibit great application potential in tissue engineering scaffolds. However, weak formation and poor mechanical property can usually be a limitation. Herein, the photo-clickable thiol-ene based chitosan were synthesized using photopolymerization maleic (MCS) thiol-terminated poly (vinyl alcohol) (TPVA) presence biocompatible photoinitiator. Rheological absorbing behavior MCS/TPVA could tailored by varying amount TPVA feed. There was strong intermolecular hydrogen bonding between molecules MCS TPVA. Notably, hydrogel (MT-3) exhibited rapid gelation (
