“…The polymers chitosan and xanthan gum are classified as polyelectrolytes because they have potentially ionizable groups, which form a PEC by complexation reaction. The reaction between chitosan and xanthan gum occurs due to ionic interactions between opposite charges present in these biopolymers, NH 3 + group of chitosan and COO − group of xanthan gum, and molecular interactions between the polymer chains (Horn and others ). The molecular properties of the polymeric complex formed by chitosan and xanthan gum can be influenced by several factors being the most known: changing the complexation conditions (polymer concentration, pH of chitosan solution, mixing ratio, and complexation time), molecular weight, degree of chitosan acetylation, and pyruvic acid content of xanthan (Dumitriu ; Magnin and others ).…”

“…The mixture of oppositely charged polyelectrolytes results in polyelectrolyte complex (PEC), which exhibits peculiar physical and chemical properties, such as electrostatic interactions, that are considered stronger than secondary binding interactions (Lee and others ). Chitosan–xanthan gum PEC gels and its applications have been largely related in the literature (Chu and others ; Argin‐Soysal and others ; Horn and others ). However, the interaction of the xanthan gum with chitosan in the development of degradable films has been little investigated.…”

Films based on chitosan and xanthan gum were prepared using casting technique aiming to investigate the potential of these polymers as packaging materials. Six formulations of films were studied varying the proportion of chitosan and xanthan gum: 100:0 (chitosan:xanthan gum, w/w, C100XG0 film); 90:10 (chitosan:xanthan gum, w/w, C90XG10 film); 80:20 (chitosan:xanthan gum, w/w, C80XG20 film); 70:30 (chitosan:xanthan gum, w/w, C70XG30 film); 60:40 (chitosan:xanthan gum, w/w, C60XG40 film); and 50:50 (chitosan:xanthan gum, w/w, C50XG50 film). The total quantity of solids (chitosan and xanthan gum) in the filmogenic solution was 1.5 g per 100 mL of aqueous solution for all treatments, according to the proportion of each polymer. The films were evaluated by their functional groups, structural, thermal, morphological, physical, mechanical, and barrier properties. All films have presented endothermic peaks in the range of 122 to 175 °C and broad exothermic peaks above 200 °C, which were assigned to the melting temperature and thermal decomposition, respectively. These results demonstrated that films with xanthan gum have the highest T and Δ H. The films containing higher content of xanthan gum show also the highest tensile strength and the lowest elongation. Xanthan gum addition did not affect the water vapor permeability, solubility, and moisture of films. This set of data suggests the formation of chitosan-xanthan complexes in the films.

“…Fibrillogenesis of collagen in vitro involves the process of collagen fibril formation from its pure molecule solution under near physiological conditions, initially concentrating on the native-like fibril-containing nanocomposites for bone tissue engineering [ 18–20 ]. Actually, collagen self-assembly in the presence of polysaccharides such as alginate, chitosan and hyaluronic acid (HA) has also been well studied by the method of fibrillogenesis of these blends under mild conditions and achieved the formation of these fibrillar nanostructures [ 21 , 22 ].…”

Konjac glucomannan (KGM) is recognized as a safe material for its health-promoting benefits and thus widely used in various fields including pharmaceutical industry. In recent decades, the combination of collagen and KGM attracts more attentions for biomedical purpose, especially the hybrid films of collagen–KGM or collagen–KGM–polysaccharide. In this study, to further and deeply develop the intrinsic values of both collagen and KGM as biomaterials, a novel kind of composite hydrogel comprising collagen and KGM at a certain ratio was fabricated under mild conditions via fibrillogenesis process of the aqueous blends of collagen and KGM that experienced deacetylation simultaneously. The chemical composition, microcosmic architectures, swelling behavior, biodegradation and dynamic mechanic properties of such resulted composite hydrogels were systematically investigated. Biologic experiments, including cell culture in vitro and hypodermic implantation in vivo, were also conducted on these collagen/KGM composite hydrogels to evaluate their biologic performances. The relevant results prove that, based on collagen self-assembly behavior, this synthesis strategy is efficient to construct a composite hydrogel of collagen/KGM with improved mechanical properties, biodegradability, excellent biocompatibility and bioactivity, which are promising for potential biomedical applications such as tissue engineering and regenerative medicine.

“…Horn and coauthors [44] reported that chitosan and xanthan gum are polyelectrolytes with potentially ionizable groups, and when they are mixed in an aqueous solution, a complex is formed due to electrostatic attraction. The complexation reaction between chitosan and xanthan gum occurs due to interaction between opposite charges present in the biopolymer (NH3 + group of chitosan and xanthan gum COOgroup), and due to molecular interaction between the polymer chains.…”
