This work aimed to develop technology to produce biodegradable hybrid composite (BHC) films based on low-density polyethylene (LDPE) 115030-070 and thermoplastic starches (TPS) of various origins (corn, pea, and rice), with distilled monoglycerides as the plasticizer. The properties of the produced BHC films were studied and the optimal native starch : glycerol : monoglycerides ratio is proposed.</p></sec><sec><title>Methods</title><p>Methods. TPS and BHC films based on this material were produced from different types of native starches in laboratory extruders (Brabender and MashPlast, Russia), and the extruded melts were subjected to ultrasonic vibrations. The structure and appearance of the BHC films were studied using scanning electron microscopy and rheology. Their biodegradability was assessed by immersing them in biocompost for three months. To evaluate the mechanical performance of the BHC films produced with and without ultrasound, the changes in tensile stress and elongation at break were determined during the biodegradation process.</p></sec><sec><title>Results</title><p>Results. The BHC films had a homogeneous structure, except small agglomerates (non-melted starch grains), which did not reduce their quality. The films with monoglycerides had high tensile strength, which was comparable with low-density polyethylene. After removing samples of the BHC films from the biocompost, their tensile strength decreased by 20%, which shows their biodegradability.</p></sec><sec><title>Conclusions</title><p>Conclusions. The produced biodegradable composite films and the technology used to produce them will be applicable for the packaging industry to reduce environmental impact.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель. Совершенствование технологии создания биологически разрушаемых гибридных композиций (БГК) на основе полиэтилена низкой плотности (ПЭНП) 11503-070 и термопластичных крахмалов различного происхождения (кукурузы, гороха, риса) с новыми пластификаторами – моноглицеридами дистиллированными. Разработка технологической схемы производства БГК. Получение и исследование свойств биологически разрушаемых композиционных пленок, пластифицированных смесью дистиллированных моноглицеридов и глицерина. Выбор оптимального соотношения нативный крахмал : глицерин : моноглицериды.</p></sec><sec><title>Методы</title><p>Методы. Термопластичный крахмал и композиционные пленки получали на основе нативных крахмалов разных видов в лабораторных экструдерах фирм «Брабендер» и «МашПласт» (Россия), при этом экструдируемый расплав композиции подвергали воздействию ультразвуковых колебаний. Была изучена структура композитных пленок методом сканирующей электронной микроскопии, а также их реологические характеристики. Проведена оценка органолептических свойств композитных пленок. Способность к биоразложению композитных пленок оценивали при помощи погружения их на три месяца в биогумус. Для оценки эксплуатационных свойств БГК, до и после процесса биоразложения, определяли разрушающее напряжение при растяжении и относительное удлинение при разрыве, причем оценка была проведена и для пленок, которые подвергали воздействию ультразвука.</p></sec><sec><title>Результаты</title><p>Результаты. Был достигнут положительный эффект от использования нового пластификатора – дистиллированных моноглицеридов в композициях термопластичный крахмал : полиэтилен. При производстве композиции получались однородными по структуре, иногда образовывались небольшие агломераты, представляющие собой нерасплавившиеся частицы крахмала, что не ухудшало качество готовых БГК. Композиты с моноглицеридами обладали высокой прочностью на разрыв – практически на одном уровне с ПЭНП. После изъятия образцов композитных пленок из биогумуса их прочность на разрыв снижалась на 20%, что свидетельствует о протекании процесса биоразложения.</p></sec><sec><title>Выводы</title><p>Выводы. Разработанный состав и технология получения биологически разлагаемых композитных пленок могут быть использованы в дальнейшем для производства композитных пленок с высоким содержанием крахмала для применения в упаковочной отрасли, что позволит снизить негативную нагрузку на окружающую среду.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>полиолефины</kwd><kwd>термопластичный крахмал</kwd><kwd>биоразлагаемые полимерные композиции</kwd><kwd>структурная модификация</kwd><kwd>экструзия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polyolefin</kwd><kwd>thermoplastic starch</kwd><kwd>biodegradable polymer composite</kwd><kwd>structural modification</kwd><kwd>extrusion</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского фонда фундаментальных исследований (проект № 19-33-90284).</funding-statement><funding-statement xml:lang="en">This work was supported by the Russian Foundation for Basic Research, project No. 19-33-90284.
