Study of Hybrid Humic Acids Modification of Environmentally Safe Biodegradable Films Based on Hydroxypropyl Methyl Cellulose
The possibility of increasing the strength and operational properties of ecologically safe biodegradable polymeric materials based on hydroxypropyl methyl cellulose by using its modification with the different types of humic acids (HAs) from lignite is considered. Hybrid ecologically safe high-strength films with antibacterial properties were obtained for the first time. Physicochemical studies and IR spectroscopy confirmed the development of hybrid structures of hydroxypropyl methyl cellulose, modified with the different types of HAs.
