жидкого кристалла в порах пористой плёнки. Данный метод основан на измерении
зависимости электрической ёмкости композиционного образца (пористая плёнка,
заполненная жидким кристаллом) от температуры. В качестве пористой структуры
была выбрана пористая полиэтилентерефталатная плёнка из-за возможности созда-
ния пор заданной ориентацией и заданными радиусами. В измерениях использова-
лись образцы пористой плёнки с радиусами пор 75, 170, 210, 300 и 425нм. В экспе-
риментах была использована оригинальная конструкция ячейки, в которой поверх-
ности пористой плёнки были покрыты токопроводящим слоем. Теоретические рас-
чёты, выполненные на основе экспериментальных данных, показали, что ориента-
ционная структура жидкого кристалла внутри пор характеризуется выходом дирек-
тора из плоскости нормальной к оси поры.</p></abstract><trans-abstract xml:lang="en"><p>The paper describes a method of detection orientational structure of liquid
crystals inside a pore of porous film. Measurement of electric capacity of
composite material (porous film is filled with liquid crystals) in dependence on
temperature is main principle of this method. Porous polyethylene terephthalate
films (track membranes) were used in experiments because of fabrication of different
pores radius and orientation is easy. The porous films with different pores
radius 75, 170, 210, 300 and 425nm were investigated. New type of liquid crystal
cell was used in experiments. Surfaces of the porous films were covered by conducting
electrodes. Results of a theoretical calculation based on the experimental
data shown that escaped radial structure of liquid crystal formed in pores of polyethylene
terephthalate films.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Пористые полимерные плёнки</kwd><kwd>жидкие кристаллы</kwd><kwd>ориентационная структура ЖК</kwd><kwd>диэлектрические измерения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polymer porous films</kwd><kwd>liquid crystals</kwd><kwd>orientational LC structure</kwd><kwd>dielectric measurements</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">Apel, P.
