Abstract
The structural model of heat expansion of polymer nanocomposites, filled with 2D-nanofiller, using the fractal analysis notions was proposed. It has been shown that linear coefficient of thermal expansion of these materials depends linearly on reciprocal of the most general characteristic of polymer nanocomposites, namely, their reinforcement degree. This means, that the heat expansion of polymer nanocomposites is defined by two parameters – nanofiller content and structure of its aggregates in polymer matrix, characterizing by their fractal dimension, that makes this model maximally simple and clear from the physical point of view. Such approach to simulation allows quantitative description and prediction of heat expansion coefficient of polymer nanocomposites, that is very important from the practical point of view.
