EFFECT OF THE PHASE STATE OF A POLYMER MATRIX ON THE DEGREE OF REINFORCEMENT OF POLYMER ORGANOCLAY NANOCOMPOSITES
RESUMO
The article shows that a significant decrease in the modulus of elasticity of a polymer matrix in its transition from a vitreous state to an elastomeric state determines the same decrease in the modulus of elasticity of organoclay tactoids. An increase in the efficiency of a nanofiller for elastomeric matrices in comparison with vitreous matrices is conditioned by the change in the nanocomposite structure as a whole, characterized by its fractal dimensionality. The effectiveness of a nanofiller is determined by its ability to generate interfacial regions. The mixture rule in its simplest form correctly describes the modulus of elasticity of nanocomposites, provided that the real, rather than the nominal modulus of elasticity of organoclay tactoids is used.
