Изучить влияние состава и концентрации раствора полимерной композиции на структуру волокон и физико-механических характеристик матриц, получаемых методом электростатического формования.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Изготовлены матрицы на основе биодеградируемых полимеров: полигидроксибутировалерата (ПГБВ), поликапролактона (ПКЛ) и поли-D,L-лактида (ПЛА) методом электроспиннинга (ЭС) из растворов ПГБВ, ПГБВ/ПКЛ и ПБГВ/ПЛА в концентрации 6, 8 и 10 %. Исследовали механические свойства матриц, диаметр волокон и размер пор.</p></sec><sec><title>Результаты</title><p>Результаты. Концентрация раствора полимера значительно влияет на диаметр волокон, формируемых в процессе ЭС, при этом не оказывая существенного влияния на размер образуемых пор. Использование 6 % раствора полимеров не позволяет получать полноценные волокна, что негативно отражается на их морфологии и физико-механических свойствах. Для создания матриц на основе ПГБВ, ПЛА и ПКЛ оптимальнее всего использовать концентрацию раствора 8–10 %. Добавление к ПГБВ ПЛА уменьшает диаметр волокон и размер пор, а включение в полимерную композицию ПЛА приводит к увеличению эластичности матриц.</p></sec><sec><title>Заключение</title><p>Заключение. Состав полимерной композиции и концентрация раствора оказывают существенное влияние на размер пор, структуру и диаметр волокон, формируемых в процессе электроспиннинга, что в свою очередь сказывается на физико-механических свойствах получаемых матриц.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose. To investigate the composition and concentration of the polymer solutions on structure and physico-mechanical properties of the electrospun scaffolds.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. We prepared electrospun scaffolds from poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), polycaprolactone (PCL), and poly(D,L-lactide) (PLA) in concentrations of 6, 8, and 10 %. We investigated mechanical properties of the scaffolds, fiber diameter, and pore size.</p></sec><sec><title>Results</title><p>Results. Concentration of the polymer solution significantly affected fiber diameter but not pore size. The optimal concentrations of PHBV, PLA, and PCL were 8–10 %. Use of PHBV/PLA composition lowered fiber diameter and pore size whilst PHBV/PCL composition increased elasticity of the scaffolds.</p></sec><sec><title>Conclusion</title><p>Conclusion. Composition and concentration of the polymer solutions significantly affects pore size, structure, and diameter of electrospun scaffolds, that influences physico-mechanical properties of the scaffolds.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>матрицы</kwd><kwd>биодеградируемые полимеры</kwd><kwd>электроспиннинг</kwd><kwd>пористость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>scaffolds</kwd><kwd>biodegradable polymers</kwd><kwd>electrospinning</kwd><kwd>porosity.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Астапов Д.
