“…PVA is chemically and thermally stable [44] and is resistant to degradation under most physiological environments [41]. Moreover, it is water-soluble due to its elevated polarity, non-toxicity [45], and high biocompatibility [46,47] and it can be processed easily [48]. PVA has also promising potential for producing biodegradable films [49].…”

Polyvinyl alcohol/carboxymethyl cellulose (PVA/CMC) composites have attracted considerable attention due to the synergic relation between the two polymers and developing novel blends with improved properties. On one hand, PVA is a versatile polymer with higher mechanical properties compared to CMC. On the other hand, CMC has high biodegradability and biocompatibility, while suffering from poor mechanical properties. Therefore, the blending of the two polymers can help to benefit from the individual component properties. This paper has reviewed the properties and potential applications (e.g. drug delivery, food packaging, and agriculture) of the PVA/ CMC composites.

“…The prepared fiber O-1 shows the stretching vibration peaks of O-H and C=O of the AA structural unit at 3221 [ 20 ] and 1695 cm −1 [ 21 ], as described in Figure 1 ; additionally, the FTIR curve of fiber O-1 shows a peak at 1161 cm −1 , which is caused by the stretching vibration of C-O in C-O-C of the HEMA structural unit [ 22 ]. Erythritol has three characteristic peaks, which are located at 3221, 1236, and 1057 cm −1 , corresponding to the stretching vibration of O-H [ 20 ], the in-plane bending vibration of O-H [ 23 ], and the stretching vibration of C-O in C-O-H [ 22 ]. In contrast to fiber O-1, fiber J-1 shows the stretching vibration peak of C-O in C-O-H at 1057 cm −1 , indicating that erythritol is introduced into fiber J-1.…”

Polytetrafluoroethylene emulsion was ultrasonically mixed with an extremely spinnable poly(acrylic acid-co-hydroxyethyl methacrylate) solution to get a dispersion with good spinnability, and the obtained dispersion was then wet-spun into water-swellable fiber. Crosslinking agents and iron species were simultaneously introduced into the water-swellable fiber through simple impregnation and water swelling. A composite fiber with Fenton reaction-catalyzing function was then fabricated by sequentially conducting crosslinking and sintering treatment. Due to crosslinking-induced good resistance to water swelling and PTFE component-induced hydrophobicity, the composite fiber showed a highly stable activity to catalyze H2O2 to oxidatively decolorize methylene blue (MB). Within nine cycles, the composite fiber could decolorize more than 90% of MB within one minute in the presence of H2O2 and did not show any attenuation in MB decolorization efficiency. The composite fiber still could reduce the total organic carbon of MB aqueous solution from 18.3 to 10.3 mg/L when used for the ninth time. Therefore, it is believable that the prepared fiber has good and broad application prospects in the field of dye wastewater treatment.

“…In turn, Wahba et al investigated the effect of CMC on Alzheimer's disease. They proved that a CMC consisting layer delays the release of galanthamine and nanoceria in vitro [194]. The CMC derivative named methylated dimethyl-amino-benzyl chitosan (TM-Bz-CS) was tested by Hakimi et al [195] in the context of Human Embryonic Kidney cells (Hek293).…”

Chitosan is one of the most well-known and characterized materials applied in tissue engineering. Due to its unique chemical, biological and physical properties chitosan is frequently used as the main component in a variety of biomaterials such as membranes, scaffolds, drug carriers, hydrogels and, lastly, as a component of bio-ink dedicated to medical applications. Chitosan’s chemical structure and presence of active chemical groups allow for modification for tailoring material to meet specific requirements according to intended use such as adequate endurance, mechanical properties or biodegradability time. Chitosan can be blended with natural (gelatin, hyaluronic acid, collagen, silk, alginate, agarose, starch, cellulose, carbon nanotubes, natural rubber latex, κ-carrageenan) and synthetic (PVA, PEO, PVP, PNIPPAm PCL, PLA, PLLA, PAA) polymers as well as with other promising materials such as aloe vera, silica, MMt and many more. Chitosan has several derivates: carboxymethylated, acylated, quaternary ammonium, thiolated, and grafted chitosan. Its versatility and comprehensiveness are confirming by further chitosan utilization as a leading constituent of innovative bio-inks applied for tissue engineering. This review examines all the aspects described above, as well as is focusing on a novel application of chitosan and its modifications, including the 3D bioprinting technique which shows great potential among other techniques applied to biomaterials fabrication.
