Multifunctional blend membranes composed of PVA and F-CMCS have been successfully developed for wound dressing applications, exhibiting good antibacterial activity, biocompatibility, and hemolysis. The potential use of these membranes in wound care is highlighted by their comprehensive properties.
Multifunctional blend membranes composed of poly (vinyl alcohol) (PVA) and fungal mushroom-derived carboxymethyl chitosan (F-CMCS) were produced using a simple solution casting technique for wound dressing applications. The structural interactions between PVA and F-CMCS were confirmed by Fourier infrared spectroscopy. The crystallinity of the membranes was examined by X-ray diffraction. Field emission scanning electron microscopy confirmed the homogeneity and coarser texture with a porous-like network in the internal structure of the membranes. The hydrophilicity, swelling, and degradation of the fabricated membranes were examined according to the F-CMCS content. The PVA/F-CMCS membrane displayed potential antibacterial activity against Escherichia coli (gram-negative) and Staphylococcus (gram-positive) bacteria. An in vitro cell study of skin fibroblasts and keratinocytes on the PVA/F-CMCS membranes confirmed the biocompatibility. The hemolysis assay demonstrated the hemocompatibility of the developed membranes. The antibacterial, biocompatibility, and good hemolysis in the PVA membrane were influenced by the F-CMCS composition ratio up to 40%. The allinclusive properties of the PVA/F-CMCS membranes highlight its potential use in wound dressing applications.
