“…Finally, it is worth recalling an important fact for predicting the properties of CNT fibers. As is known [13], in the case of polymer nanocomposites, their elastic modulus at a fixed nanofiller content is determined only by the structure of nanofiller in the polymer matrix, characterized by the fractal dimension of nanofiller aggregates. In this case, increase of D f determines the growth of elastic modulus.…”

The theoretical model, treating increasing of elastic modulus of fibers from carbon nanotubes at introduction of transverse π-π-bridging between separate nanotubes in fiber. It has been shown that on elastic modulus of fiber three factors influenced, namely, elastic modulus of starting nanotubes, level of interactions between separate nanotubes in fiber and its aspect ratio, i.e. the ratio of fiber length to its diameter. In transition point of the indicated interactions from repulsion to attraction the elastic modulus of fiber achieves the value of corresponding parameter individual carbon nanotube and in region of attractive interactions exceeds it. The structure of fibers, characterized by their fractal dimension, is basic factor for stiffness of fibers of carbon nanotubes. Keywords: fiber, carbon nanotubes, π-π-bridging, nanotubes interactions, structure, elastic modulus, fractal dimension.

“…Величину η ор следует принять постоянной и равной ~ 0,38 или 3/8 [1,2]. При моделировании кольцеобразных формирований углеродных нанотрубок как макромолекулярных клубков справедливо следующее соотношение [10]: (6) где А -длина «участка жесткости» кольцеобразного формирования нанотрубок, который является аналогом сегмента Куна в случае макромолекулярных клубков.…”

Показано, что простое правило смесей корректно описывает модуль упругости нанокомпозитов полимер/углеродные нанотрубки, если используются не номинальные, а реальные характеристики нанонаполнителя. Указанные характеристики определяются структурой углеродных нанотрубок в полимерной матрице. Основной вклад в жесткость нанокомпозитов вносит фактор эффективной длины (аспектного отношения) углеродных нанотрубок.Ключевые слова: нанокомпозит, углеродные нанотрубки, правило смесей, ориентация, эффективная длина, степень усиленияIt is shown that the simple rule of mixtures describes correctly the elastic modulus of polymer/carbon nanotubes nanocomposites, if the real characteristics of the nanofi ll are used instead of the nominal ones. These characteristics are determined by the structure of carbon nanotubes in the polymer matrix. The factor of eff ective length (aspect ratio) of carbon nanotubes pays the main contribution to nanocomposites stiff ness.
