Методами сканирующей электронной микроскопии и измерения шероховатости пленок установлено, что наибольшую шероховатость имеют пленки, полученные из смеси КМЦ-желатин. Показано, что введение КМЦ в состав пленок желатина приводит к резкому уменьшению прочности и модуля упругости пленок, однако деформация имеет максимальное значение при массовом соотношении КМЦ / желатин, равном 0,7. Это обусловлено образованием биокомпозитов за счет Н-связей и электростатических взаимодействий между функциональными группами белков желатина и макромолекул полисахарида, стабилизированных гидрофобными взаимодействиями между их неполярными участками. Изучены барьерные свойства пленок на основе КМЦ и желатина. Показано, что наибольшую воздухопроницаемость и наименьшую водоупорность имеют пленки на основе КМЦ, что связано с текстурированностью материала пленок. На основе данных ИК-спектроскопии установлено, что наиболее устойчивыми являются пленки, полученные из смеси КМЦ и желатина. Для регулирования деформации пленок использован глицерин.</p></abstract><trans-abstract xml:lang="en"><p>Biodegradable gelatin-based films have been obtained in the presence of carboxymethylcellulose (CMC) additives intended for use as packaging of food products and drug carriers. By methods of scanning electron microscopy and measurement of film roughness, it was found that films obtained from a mixture of CMC and gelatin have the greatest roughness. It is shown that the introduction of CMC into the composition of gelatin films leads to a sharp decrease in the strength and modulus of elasticity of the films, however, the deformation has maximum values at a mass ratio of CMC / gelatin equal to 0.7. This is explained by the formation of associates due to H-bonds and electrostatic interactions between functional groups of gelatin proteins and polysaccharide macromolecules, stabilized by hydrophobic interactions between their nonpolar sites. The barrier properties of films based on CMC and gelatin have been studied. It is shown that CMC-based films have the highest air permeability and the lowest water resistance, which is due to the texture of the film material. Based on IR spectroscopy data, it was found that films obtained from a mixture of CMC and gelatin are the most stable. Glycerin was used to regulate the deformation of the films.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биоразлагаемые пленки</kwd><kwd>желатин</kwd><kwd>карбоксиметилцеллюлоза</kwd><kwd>структурообразование</kwd><kwd>прочность</kwd><kwd>шероховатость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biodegradable films</kwd><kwd>gelatin</kwd><kwd>carboxymethylcellulose</kwd><kwd>structure formation</kwd><kwd>strength</kwd><kwd>roughness</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках гранта AP19677207 «Дизайн наноструктурированных бионанокомпозитов на основе природного сырья», финансируемого Комитетом науки МНВО РК.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Brito T.B., Carrajola J.F., Gonçalves E.C.B.A., Martelli-Tosi M., Ferreira M.S.L.
