“…Noted that Yang et al have prepared a PVA/chitosan/graphene oxide composite and found this composite is better for inhibiting the Escherichia coli ( E. coli ). [ 57 ] This difference is however reasonable from the used graphene. [ 57 ] Of interesting, a comparison found that the PVA/TP composite with only 5% TP has presented obviously enhanced antibacterial properties than Yang et al reported values.…”

Several fully green composites are prepared by taking the tea polyphenols (TP) with various percentages to blend with poly(vinyl alcohol) (PVA). The as‐prepared PVA/TP composite with only 5% TP shows superb anti‐UV properties even after water washing, the presented UV protection factor (UPF) value is still greater than that of the standard values reported by Australia and New Zealand (AS/NZS 4399‐1996). Moreover, the UPF value of those PVA/TP composites is found capable of furthermore enhancement by increasing the TP percent. This PVA/TP composite also shows good antibacterial and biodegradability while it is kept with certain mechanical properties to fit required application cases.

“…Pandele et al11 utilized a casting method to prepare PVA, CS, and graphene oxide (GO) films, which displayed improved mechanical properties and sufficient biocompatibility. Marin et al12 and Yang et al13 prepared porous PVA/CS/GO membranes with good antibacterial activity and biocompatibility via electrospinning methodology. Ruiz et al14 developed the PVA/CS/GO antibacterial film with adequate degradation in vivo.…”

Rapid absorption of wound exudate and prevention of wound infection are prerequisites for wound dressing to accelerate wound healing. In this study, a novel kind of promising wound dressing is developed by incorporating polyhexamethylene guanidine (PHMG)‐modified graphene oxide (mGO) into the poly(vinyl alcohol)/chitosan (PVA/CS) matrix, conferring the dressing the required mechanical properties, higher water vapor transmission rate (WVTR), less swelling time, improved antibacterial activity, and more cell proliferation compared to the PVA/CS film crosslinked by genipin. In vivo experiments indicate that the PVA/CS/mGO composite film can accelerate wound healing via enhancement of the re‐epithelialization. PVA/CS/mGO composite film with 0.5 wt% mGO sheets displays the best wound healing properties, as manifested by the 50% higher antibacterial rate compared to GO and the wound healing rate of the mouse using this dressing is about 41% faster than the control group and 31% faster than the pure PVA/CS dressing. The underlying mechanism of the accelerated wound healing properties may be a result of the improved antibacterial ability to eradicate pathogenic bacteria on the wound area and maintain an appropriate moist aseptic wound healing environment to accelerate re‐epithelialization. These findings suggest that this novel composite PVA/CS/mGO film may have promising applications in wound dressing.

“…The use of composite films for food packaging applications helps reduce the adverse effects of using plastic bags, such as fossil fuel consumption and soil and water pollution [1,2]. Targeted selection of raw materials can allow the fabrication of composite films with special properties, such as antibacterial properties and biodegradability [3,4], making them effective for food packaging applications.…”

Preparation and Properties of Sodium Carboxymethyl Cellulose/Sodium Alginate/Chitosan Composite Film

2018

A sodium alginate/chitosan solution was prepared by dissolving sodium alginate, chitosan, and glycerol in an acetic acid solution. This solution was then combined with a sodium carboxymethyl cellulose solution and the mixture was cast onto a glass plate and dried at a constant temperature of 60 • C. Then, a carboxymethyl cellulose/sodium alginate/chitosan composite film was obtained by immersing the film in a solution of a cross-linking agent, CaCl 2 , and air-drying the resulting material. First, the most advantageous contents of the three precursors in the casting solution were determined by a completely random design test method. Thereafter, a comprehensive orthogonal experimental design was applied to select the optimal mass ratio of the three precursors. The composite film obtained with sodium alginate, sodium carboxymethyl cellulose, and chitosan contents of 1.5%, 0.5%, and 1.5%, respectively, in the casting solution displayed excellent tensile strength, water vapor transmission rate, and elongation after fracture. Moreover, the presence of chitosan successfully inhibited the growth and reproduction of microorganisms. The composite film exhibited antibacterial rates of 95.7% ± 5.4% and 93.4% ± 4.7% against Escherichia coli and Staphylococcus aureus, respectively. Therefore, the composite film is promising for antibacterial food packaging applications.
