Nano-Ag/DLC/Cellulose Free-Standing Films Towards Anti-bacterial and Bio-compatible Futuristic Bandage Applications

Nano-Ag/DLC/cellulose composite free-standing films were deposited by using hybrid chemical routes. Cellulose fibers were extracted from banana pseudostem fibers by chemical route. Modulation of bonding environment on cellulose upon nano-Ag and diamond-like carbon (DLC) inclusions was studied by X-ray photoelectron spectroscopy (XPS), Raman and Fourier transformed infrared spectroscopy (FTIR) measurements. Changes in microstructural and bonding environmental properties of the cellulose films with nano-Ag and DLC loadings were also addressed. These composite films would harness the development of anti-bacterial and bio-compatibility in futuristic bandage applications. Antibacterial studies using Staphylococcus aureus (gram positive) and Escherichia coli (gram negative) bacteria were carried out on the above n-Ag/DLC/cellulose composite films.
