This approach includes the process of deformation of the pristine films of ultra-high molecular weight polyethylene <italic>via</italic> environmental intercrystallite crazing mechanism and subsequent low-temperature spontaneous strain recovery upon stress relaxation. As a result, the material acquires new properties typical for hard elastic materials: restoration of the porous structure upon secondary loading in air up to ~20 vol. % with pore sizes in the nanometer range (up to 10 nm), high reversibility of deformation (50−85%), the effect of opening and closing pores upon cyclic loading. The mechanism of this phenomenon has been proposed and the areas of practical applications of such mechanoresponsive material have been indicated.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181323998624">Предложен новый подход к созданию жестко-эластичного полимерного материала на основе сверхвысокомолекулярного полиэтилена с использованием стратегии крейзинга полимеров. Данный подход включает в себя процесс деформирования исходных пленок сверхвысокомолекулярного полиэтилена по механизму межкристаллитного крейзинга и последующий процесс низкотемпературной обратимой деформации при снятии напряжения. В результате материал приобретает новые свойства, типичные для жестко-эластичных материалов: восстановление пористой структуры при повторном деформировании на воздухе до ~20 об. % с размерами пор в нанометровом диапазоне (менее 10 нм), высокая обратимость деформации (50–85%), эффект открытия и закрытия пор при нагружении в циклическом режиме. Предложен механизм данного явления и обозначены области практического использования такого рода механочувствительного материала.</p></trans-abstract><kwd-group xml:lang="en"><kwd>ultra-high molecular weight polyethylene</kwd><kwd>crazing</kwd><kwd>mesoporous structure</kwd><kwd>hard elastic polymeric material</kwd><kwd>mechanoresponsive polymeric materials</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>сверхвысокомолекулярный полиэтилен</kwd><kwd>крейзинг</kwd><kwd>мезопористая структура</kwd><kwd>жестко-эластичный полимерный материал</kwd><kwd>механочувствительные полимерные материалы</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kurtz S.M.
