CONDITIONS FOR THE CREATION OF HIGH-MODULUS POLYMER/CARBON NANOTUBES NANOCOMPOSITES
ABSTRACT
The factors determining the creation of high-modulus polymer/carbon nanotubes nanocomposites are investigated within the framework of percolation and fractal reinforcement models. It is shown that the degree of reinforcement (or the elasticity modulus) of the nanocomposite is controlled by three main factors: the structure of the nanofiller in the polymer matrix, its volumetric content, and the elasticity modulus of the matrix polymer. The structure of carbon nanotubes (or their ropes), characterized by its fractal dimensionality, is determined by the total influence of two types of interactions: polymer matrix-nanofiller and the interaction of carbon nanotubes within their rope. To obtain high-modulus polymer/carbon nanotubes nanocomposites, attraction interactions between carbon nanotubes are required.
