“…The peaks obtained for all samples are typical for cellulose-I structure [ 23 ]. All plots exhibit peaks located near 1095 cm −1 , which is characteristic for cellulose materials and corresponds to C-O ring stretch modes within cellulose backbone [ 24 , 25 ]. A number of peaks located in the region ranging from 1200 to 1450 cm −1 are attributed to modes involving considerable coupling of methine bending, methylene rocking and wagging, and C-O-H in-plane bending vibrations [ 23 ].…”

Here, we aimed to boost antibacterial performance of cellulose fibers for paper sheet application. Therefore, TiO2 nanoparticles have been used with controlled loading onto the surface of the fibers. A simple and facile composite preparation route based on ultrasound and mechanical assisted stirring has been developed. We tested cellulose paper enriched by TiO2 from 1.0 wt% to 8.0 wt%, respectively. Antibacterial performance has been studied against Staphylococcus aureus and Escherichia coli bacteria. Studies showed that all composites exhibit significant capability to reduce living cells of S. aureus and E. coli bacteria at least 60%. The simplicity, low cost, and reproducibility of the prepared method indicates the potential to be scaled up for industrial applications.

“…However, many of these toxic, corrosive, non‐degradable, or even mutagenic solvents may migrate into food matrices 9 . Few recent studies have offered alternative fewer toxic solvents 10,11 or have described the fabrication of composite chitin films 12,13 . Mechanochemical methods have improved the conversion of chitin.…”

Chitin is a valuable natural material, but its applications are limited because of its insolubility in water. Size reduction of natural materials has been found to offer certain benefits, including enhancing dispersibility. We employed media milling to produce a chitin micro‐suspension with water as the sole solvent, and to fabricate the chitin film. The particle size and molecular weight were decreased from 96.86 to 21.95 μm and 173 to 75 kDa (Mn), respectively, post milling; however, the degree of deacetylation slightly increased (from 21.26 to 24.31) with milling time. Moreover, limited water‐soluble fractions were generated, the quantity (1.5–2.0% d.b.) and molecular weight (Mn 15–34 kDa) of which were characterized. These fractions enabled the formation of a chitin film through the induction of hydrogen bonds. The particle size affected the morphology and mechanical properties of the film. The fabricated chitin film had tunable thickness (61.3–80.7 μm), tensile strength (38.95–64.61 MPa), elongation (0.93%–2.16%), Young's modulus (2994–4246 MPa), WVP (12.04–17.79 g mm/m2 day kPa), swelling ratio and surface smoothness. This novel method for fabricating chitin films through aqueous suspension can improve applications of chitin in packaging and particularly fulfill environmentally friendly requirements.
