Abstract This study aims to transform post-consumer textile waste (cellulosic materials) into viscose fiber using a xanthation technique, as well develop value-added antibacterial chitosan functionalized (CFV) for biomedical applications (e.g., sanitary pad) through an economic up-cycling wet spinning integrated coating approach. Surface morphology (SEM), FTIR, XRD, mechanical, thermal, and properties (both gram-positive gram-negative bacteria) were investigated the CFV fiber. The Degree of Polymerization (DP) raw (RV) was approximately 782 ± 35, comparable DP commercial fibers. surface is uneven, hazy, rough, its average diameter 15.65 1.75 μm, which higher than fibers have stronger strength RV fibers, demonstrated by creation hydrogen bonds with fundamental reason strength.. Overall, effects (zone inhibition) against E. c oli, S.Typhi, S.aureus are 17 1.2 mm, 13 0.8 10 1.1 respectively. However, development process results confirm successful formation highlight potential sustainable compared other alternatives.

Nowadays, plastic contamination worldwide is a concerning reality that can be addressed with appropriate society education as well looking for innovative polymeric alternatives based on the reuse of waste and recycling circular economy point view, thus taking into consideration future world without quite impossible to conceive. In this regard, in review, we focus sustainable materials, biodegradable bio-based polymers, additives, micro/nanoparticles used obtain new environmentally friendly polymeric-based materials. Although polymers possess poorer overall properties than traditional ones, they have gained huge interest many industrial sectors due their inherent biodegradability natural environments. Therefore, several strategies been proposed improve extend applications. Blending strategies, development composites nanocomposites, shown promising perspectives improving performances, emphasizing biopolymeric blend formulations micro nanoparticles produce fully The Review also summarizes recent developments blends, composites, nanocomposite plasticization, particular naturally derived plasticizers chemical modifications increase compatibility matrices. current state art most important reviewed, mainly focusing synthesis processing methods scalable sector, such melt solution blending approaches like melt-extrusion, injection molding, film forming electrospinning, among others, neglecting degradation processes.

Chitosan is widely used in drug delivery applications, due to its biocompatibility, bio-degradability, and low toxicity. Nevertheless, properties can be enhanced through the physical or chemical modification of amino hydroxyl groups. This work explores electrostatic complexation two chitosan samples differing lengths with poly(N-isopropylacrylamide) (PNIPAM) homopolymers different molecular weight carrying a chargeable carboxyl end group. interaction enables binding PNIPAM side chains onto backbone groups, could considered as an alternative grafting method. Dynamic electrophoretic light scattering techniques were employed order study solution/dispersion formed complexes function concentration, or, equivalently, molar/charge ratio components. The obtained results revealed that their mass, size, charge mostly depend on length individual constituents, well mixing ratio. Furthermore, response changes environment, namely temperature ionic strength, was also examined, demonstrating effect either thermoresponsiveness screening, respectively. Fluorescence spectroscopy, utilizing pyrene probe, provided information regarding hydrophobicity complexes, while images from scanning transmission electron atomic force microscopies further elucidated morphology, which found closely related corresponding molecule. Finally, potential vehicles investigated, curcumin model at various loading concentrations.
