This variation of tactoids structural state is due to interfacial interactions. It has been shown within the framework of reinforcement percolation theory, that structure of tactoids is single factor, defining reinforcement efficiency is characterized by its ability to create interfacial regions.</p></abstract><trans-abstract xml:lang="ru"><p>Предложена методика характеризации структуры тактоидов 2D-нанонаполнителя в полимерной матрице нанокомпозита, которая показала, что указанные тактоиды являются фрактальными объектами с размерностью 1,75-2,16. Эта вариация структурного состояния тактоидов обусловлена межфазными взаимодействиями. В рамках перколяционной теории усиления показано, что структура тактоидов является единственным фактором, определяющим степень усиления нанокомпозитов. Эффективность нанонаполнителя характеризуется его способностью формировать межфазные области.</p></trans-abstract><kwd-group xml:lang="en"><kwd>nanocomposite</kwd><kwd>2D-nanofiller</kwd><kwd>structure</kwd><kwd>fractal analysis</kwd><kwd>interfacial regions</kwd><kwd>percolation</kwd><kwd>reinforcement degree</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>нанокомпозит</kwd><kwd>2D-нанонаполнитель</kwd><kwd>структура</kwd><kwd>фрактальный анализ</kwd><kwd>межфазные области</kwd><kwd>перколяция</kwd><kwd>степень усиления</kwd></kwd-group><funding-group><award-group><award-id></award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Schaefer D.W., Zhao J., Dowty H., Alexander M., Orler E.B. // Soft Mater. 2008.
