“…The CTS spectrum revealed the characteristic overlapping vibration signals of the hydroxyl (-OH − ), amino (−NH 2 ) and amide (−CONH 2 ) functional groups at 3412 cm −1 . Also, bands of the asymmetric stretching of the methyl groups (−CH 3 ) were observed at 2924 cm −1 , the stretching of the carbonyl group (C=O) at 1655 cm −1 , the band of −CONH 2 at 1557 cm −1 [13], the secondary stretching of the OH − group at 1378 cm −1 , the C-N stretching of type III amides at 1320 cm −1 and the stretching of the glycosidic bond (C−O−C) at 1083 cm −1 [25,30]. The broad band between 3500 and 3200 cm −1 is characteristic of the stretching of the −NH 2 groups overlapped with OH − groups [57].…”

“…On the other hand, poly (lactic acid) (PLA), collagen and chitosan (CTS), are biodegradable polymers, respectively, that have been used for electrospun fiber manufacture and, among them, CTS stands out due to its antiseptic properties [10][11][12]. CTS, whose chemical name is poly [β-(1-4)-2-amino-2deoxy-D-glucopyranose], is obtained from the chemical modification of chitin [13]. Chitin is the second-most abundant polysaccharide in nature after cellulose, and is present in the shells of crustaceans, fungi and insects [14].…”

A viable alternative for the next generation of wound dressings is the preparation of electrospun fibers from biodegradable polymers in combination with inorganic nanoparticles. A poly(vinyl alcohol)-chitosan-silver nanoparticles (PVA-CTS-Ag NPs) system has been developed for antimicrobial and wound healing applications. Here, the preparation of PVA-CTS-Ag electrospun fibers using a two-step process is reported in order to analyze changes in the microstructural, mechanical, and antibacterial properties and confirm their potential application in the biomedical field. The Ag nanoparticles were well-dispersed into the chitosan matrix and their cubic structure after the electrospinning process was also retained. The Ag NPs displayed an average diameter of ~33 nm into the CTS matrix, while the size increased up to 213 nm in the PVA-CTS-Ag(NPs) fibers. It was observed that strong chemical interactions exist between organic (CTS) and inorganic phases through nitrogenous groups and the oxygen of the glycosidic bonds. A defect-free morphology was obtained in the PVA-CTS-Ag NPs final fibers with an important enhancement of the mechanical properties as well as of the antibacterial activity compared with pure PVA-CTS electrospun fibers. The results of antibacterial activity against E. coli and S. aureus confirmed that PVA-CTS-Ag(NPs) fibers can be potentially used as a material for biomedical applications.

“…[ 18 ] It consists of repeatable N ‐acetyl‐D‐glucosamine units linked by β‐(1 → 4) glycosidic bonds (Figure S1[b]). [ 19 ] The properties of CS such as biodegradability, biocompatibility, nontoxicity, antioxidant, bioactivity, antifungal activity, high mechanical strength, and excellent film‐forming feature are similar to PVA. [ 15,18–20 ] Besides, CS is often being used together with PVA in different applications [ 21 ] including water‐induced shape memory application.…”

In this study, we successfully prepared poly (vinyl alcohol)/chitosan/sodium alginate blended (PCS/SA) composite membranes by a simple solution casting method and solvent evaporation technique. The physicochemical properties and effect of different wt% of sodium alginate (SA) on poly (vinyl alcohol)/ chitosan (PCS) membranes were systematically evaluated and studied along with its shape memory properties and mechanism. With increased wt% of SA, the crystallinity of PCS/SA membranes reduced significantly. PCS/SA membrane has better thermal stability than pure PVA membrane but is slightly lower than PCS membrane and decreased with higher SA contents. Dynamic mechanical analysis (DMA) study revealed that water act as a stimulus for the shape recovery behavior. The mechanical study showed that PCS membranes with a small amount of SA (0.1 and 0.2 wt%) have a much better elongation at break than other membranes. The swelling ratio, gel contents, and contact angle results concurred with the results of shape memory effect (SME) of all membranes, where the PCS with higher contents of SA possess better and faster shape recovery speed. The above results demonstrate that SA is a potential additive that can be used for water-induced shape memory applications.

“…There are other mixtures with synthetic polymer of chitosan that are not included in this review, as those do not fit the sustainability criteria of the present review. Numerous composites of chitosan have been fabricated with graphene, carbon nanotubes, activated carbon, and metal nanoparticles [ 92 , 93 , 94 , 95 ]. One study suggests that poly(L-lactic acid)-ZnO multilayered with cationic chitosan and anionic β-cyclodextrin can be used as a promising material in applications for the active packaging of food [ 96 ].…”

New developments require innovative ecofriendly materials defined by their biocompatibility, biodegradability, and versatility. For that reason, the scientific society is focused on biopolymers such as chitosan, which is the second most abundant in the world after cellulose. These new materials should show good properties in terms of sustainability, circularity, and energy consumption during industrial applications. The idea is to replace traditional raw materials with new ecofriendly materials which contribute to keeping a high production rate but also reducing its environmental impact and the costs. The chitosan shows interesting and unique properties, thus it can be used for different purposes which contributes to the design and development of sustainable novel materials. This helps in promoting sustainability through the use of chitosan and diverse materials based on it. For example, it is a good sustainable alternative for food packaging or it can be used for sustainable agriculture. The chitosan can also reduce the pollution of other industrial processes such as paper production. This mini review collects some of the most important advances for the sustainable use of chitosan for promoting circular economy. Hence, the present review focuses on different aspects of chitosan from its synthesis to multiple applications.
