Functional biodegradable materials based on natural and synthetic polymers with antibacterial action

A literature review was conducted on the production of biodegradable film-forming materials made from naturally renewable raw materials with antibacterial properties. The main component ensuring the biodegradability of the compositions is thermoplastic starch. The review also describes the use of synthetic polymers as film-forming components in these compositions, including polybutylene adipate terephthalate, polylactic acid, polycaprolactone, polyethylene, polyvinyl alcohol, and polyvinylpyrrolidone. The antibacterial properties of these materials are achieved by adding chitosan, which is made soluble through treatment with acids such as acetic, lactic, and formic acid, as well as by incorporating medicinal drugs, silver nanoparticles, or essential oils.
