The methodics of characterization of 2D-nanofiller tactoids structure in polymer matrix of nanocomposite was proposed, which shown that the indicated tactoids are fractal objects with dimension of 1.75-2.16. 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.

Reinforcement Efficiency

The comparative analysis of reinforcement efficiency (modulus of elasticity enhancement) of polymers with carbon nanotubes and grapheme was performed using the methods of fractal analysis and percolation theory. It has been shown that such comparison is correct only at the same structure of the indicated anisotropic nanofillers in polymer matrix. For carbon nanotubes reinforcement efficiency depends strongly on their geometry, i.e. length and outer diameter. In addition the main role in polymers reinforcement play not initial characteristics of nanofiller, but its structures, obtained in production process of nanocomposites. In technological aspect carbon nanotubes are more suitable for manufacture of high-modulus nanocomposites, that is due to possibility of simple enough realization of their orientation.
