Эффект памяти в этих пленках регистрировался по диэлектрическому гистерезису в результате вольт-фарадных измерений. Установлено, что наблюдаемое после каждого такого измерения приращение электрической емкости снижается с ростом частоты акустического поля. При колебаниях звука на частоте 2000 Гц эффект памяти полностью исчезает за счет разрушения сетки наночастиц диоксида кремния и, соответственно, появления изотропной ориентации молекул жидких кристаллов.</p></abstract><trans-abstract xml:lang="en"><p>The effect of mechanical vibration in the frequency range from 200 Hz to 2500 Hz on the memory effect in 5CB polymer dispersed liquid crystals doped with SiO2 nanoparticles has been studied. As a result of capacitance-voltage measurements, the dependences of the dielectric properties of liquid crystal cells with 0.1 wt% SiO2 on the bias voltage. It has been established that the memory effect detected by dielectric hysteresis in polymer dispersed liquid crystals with silicon dioxide nanoparticles monotonically decreases with increasing oscillation frequency and completely disappears at a frequency of 2000 Hz due to the destruction of the network of silica nanoparticles and, respectively, the appearance of an isotropic orientation liquid crystals molecules.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>жидкие кристаллы</kwd><kwd>ПДЖК</kwd><kwd>эффект памяти</kwd><kwd>диоксид кремния</kwd><kwd>наночастицы</kwd><kwd>резонанс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>liquid crystals</kwd><kwd>memory effect</kwd><kwd>vibration</kwd><kwd>polymer films</kwd><kwd>capacity of PDLC cells</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках гранта государственного задания № 0270-2021-002.
