Rheology as a tool for evaluationof hybrid structure in thermo plastic polymer nanocomposites with graphene and carbon nanotubes

Experimental and theoretical rheology was used as a tool for characterizationof hybrid structure of thermoplastic polymer nanocomposites filled with graphene and carbon nanotubes. Different rheological approaches were applied to evaluatethe degree of nanofiller dispersion, the effect of nanofiller shape on viscosity, as well as the particle-particle and polymer-particle interactions.Rheological percolation threshold was proposed as important characteristic related to the reinforcement effects of nanofillersin polymer.
