Расчетная схема основана на предложенном уравнении, в котором энергия активации процесса проницаемости снижается при действии давления по степенной зависимости. Адекватность расчетной схемы проверена на примере проницаемости СО2 через мембраны на основе полиимидов. Найдено хорошее совпадение расчетных и экспериментальных данных по увеличению проницаемости с ростом давления. Работоспособность схемы также проверена на примере трех полиимидов для двух случаев – роста и немонотонного изменения проницаемости. Проанализировано снижение проницаемости и отсутствие зависимости от давления.</p></abstract><trans-abstract xml:lang="en"><p>The calculation scheme is proposed for analyzing the effect of pressure on the permeability of various gases through polymeric membranes. The calculation scheme is based on the proposed equation, in which the activation energy of the permeability process decreases under the action of pressure according to a power law. The adequacy of the calculation scheme was verified on the example of CO2 permeability through polyimide-based membranes. A good agreement was found between the calculated and experimental data on the increase in permeability with increasing pressure. The performance of the scheme was also tested using the example of three polyimides for two cases-growth and non-monotonic change in permeability. The decrease in permeability and the absence of dependence on pressure are analyzed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>проницаемость газов через мембраны</kwd><kwd>влияние давления на проницаемость</kwd><kwd>энергия активации процесса</kwd><kwd>полиимиды</kwd><kwd>полиамидоимиды</kwd><kwd>межмолекулярные взаимодействия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>permeability of gas through membranes</kwd><kwd>effect of pressure on permeability</kwd><kwd>process activation energy</kwd><kwd>polyimides</kwd><kwd>polyamidoimides</kwd><kwd>intermolecular interactions</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данная работа выполнена при финансовой поддержке Российского научного фонда, грант № 22-13-00066, https://rscf.ru/ project/22-13-00066.
