In this paper, the mechanical properties of hybrid chitosan hydrogels were investigated using the texture profile analysis test. Scaffolds obtained from a polysaccharide of various molecular weights were studied, which, with the addition of glycerophosphate salt, formed a three-dimensional structure in vivo. The obtained systems were also enriched with collagen and calcium carbonate to improve the...
In the present paper, results from rheological measurements and tensile tests of polymer blends containing chitosan and poly(vinyl alcohol) with different additions of an ionic liquid are presented. Flow measurements were carried out using solutions of pure polymers and their blends with and without the addition of an ionic liquid. It has been observed that the polymer solutions and their blends exhibited...
Chitosan is widely applied in biomedical and cosmetic fields. For this reason, there is a need to modify this biopolymer to achieve new properties of chitosan-based materials. The properties of chitosan can be modified by several cross-linking methods. In this work, we used the chemical cross-linking of chitosan with tannic acid, after which cross-linked chitosan was shaped into a 3D structure by...
