Investigating the effect of HTCC on SA-based hydrogel printability

N- [(۲-Hydroxyl)- propyl-۳-trimethyl ammonium] chitosan chloride (HTCC) with DS=۹۰ % wassynthesized and characterized. HTCC ۱%w and ۳%w were used with sodium alginate (SA) to preparea polyelectrolyte complex for ۳D printing. Their flow curves show that with decreasing HTCC/SAratio, apparent viscosities decrease, which was ascribed to a shielding effect of N, N,Ntrimethylammonium(–N(CH۳)۳+) On the carboxyl (–COO-) groups. The study demonstrated thatHTCC could enhance the printability of ۳D-printed hydrogel. Additionally, the interaction betweenHTCC and SA was found to be critical in determining the rheological properties of the printedmaterials. This research contributes to the development of advanced materials for ۳D printingapplications.
