Thermomechanical and mechanical properties of biocidal materials based on polyhexamethylene guanidine hydrochloride and polyvinyl alcohol

During the development of polymer science, attention has been attracted to different research areas. The current focus on polymer mixtures is due to their practical significance. Studying the physical and mechanical properties of polymer mixtures has led to a revision of existing basic concepts, the emergence of new research directions and the solution of practical problems. From this point of view, polymer mixtures are similar to copolymerization in achieving specific properties by combining different chemical structures. The use of polymer mixtures allows materials with the desired properties to be obtained at a faster rate than the synthesis of high-molecular compounds. In recent years, numerous studies have been published on the interaction of various polymers, particularly water-soluble and naturally occurring polymers that are safe for humans and the environment. The development of such materials is of great interest due to their high adhesive strength. These materials can be used to obtain polymer films with new valuable properties. This work investigates the potential of improving the thermomechanical and mechanical properties of films for use in construction as polymer biocidal additives by modifying polyhexamethylene guanidine hydrochloride with polyvinyl alcohol. Films based on a polymer-polymer mixture of polyhexamethylene guanidine hydrochloride and polyvinyl alcohol were used as a research object.
