Investigation of Hybrid Modification of Eco-Friendly Polymers by Humic Substances

Abstract

Research on investigation of hybrid eco-friendly polymers modificated by humic substances are given in this article. The purpose of the research is to investigate a hybrid modification of eco-friendly polymers of polylactic acid by humic substances, it was found that the mechanism of hybrid modification in the matrix synthesis of the polylactic acid-humic substances system indicates an intermolecular bond between polylactic acid and humic substances, at the same time, due to increased crystallization and the emergence of intermolecular and ester bonds in the formation of more rigid mesh structure in the system polylactic acid-humic substances is increasing the mechanical properties of such materials. It was found that the increase in the impact strength and the breaking stress during bending in the polylactic acid-humic substances system in the hybrid modification occurs, while the optimal content of humic substances in the polylactic acid-humic substances systems is 0.5 % by mass.
