Experimental evaluation of structure formation in solutions of biopolymer mixtures and prediction of the properties for biomedical materials obtained
The experimental evaluation of structure formation in solutions of individual polymers, as well as in their mixtures with other polymers in order to predict the properties of materials obtained on their basis was the aim of this work. We used chitosan, sodium salt of chitosan succinyl, sodium salt of carboxymethyl cellulose, and polyvinyl alcohol. Distilled water, 1 % acetic acid, and buffer systems based on acetic acid and sodium acetate with pH = 3.80, 4.25, and 4.75 were used as solvents. It was found that the type of aggregates formed in polymer mixtures is determined by the nature of the solvent and the concentration of the polymers in the initial solution. A correlation has been shown between the nature of aggregates formed in solutions and some physicochemical properties of film materials obtained from solutions, namely, the degree of enzymatic hydrolysis, as well as the rate and degree of water vapor sorption by film materials. Thus, the studies carried out show that by varying the nature of the solvent, the concentration and nature of the polymers in the initial solutions, it is possible to control the structure formation in mixed polymer solutions, and, therefore, the properties of the resulting composites.
期刊介绍:
The aim of "Letters on materials" is to provide a fast publication of short research and review articles on various topics in materials science and related areas of material physics and mechanics. The editorial board sees it''s own task in rapid informing of the readers on the state-of-the-art challenges and achievements in materials science. The editorial board does its best to select high quality papers reporting new scientific results that are of interest for researchers in materials science, physics, and mechanics. "Letters on materials" invites Russian and foreign researches to publish papers in both the Russian and English languages. The scope of the journal covers the following research areas: structure analysis of materials, mechanical and physical properties of materials, production and processing of materials, experimental methods of investigation of materials, theory and computational methods in solid state physics. "Letters on materials" is designed for researchers, engineers, lecturers, and students working in the areas of materials science, mechanical engineering, metal forming, physics, and material mechanics.
