Tough chitosan hydrogel based on purified regeneration and alkaline solvent as biomaterials for tissue engineering applications

The chitosan based on purified regeneration could be dissolved in 6 wt% aqueous NaOH without freeze-thawing cycles and acetylation processing, and such a solution system was effective and different from other dissolving methods Upon heating, a tough hydrogel was constructed from the chitosan (purified regeneration) alkaline solution. The results of XRD, TEM, SEM and rheology analysis proved that chitosan easily aggregated in the solution and...
