Mechanisms of Stack Interaction in Polymer Composites of Polyvinylchloride with Methylene Blue

摘要

1 Introduction Polymers play an important role in various science-intensive industries. At the same time, they have a number of disadvantages, including those caused by low mechanical, electrically conductive properties. Overcoming these disadvantages is realized through the synthesis of polymers with internal conductivity or by filling the polymer matrix with conductive particles, including various carbon nanostructures to create external electrical conductivity and improve mechanical characteristics [1, 2]. The filling with the carbon nanostructures, primarily nanotubes and graphene plates leads to the percolation effect of increasing electrical conductivity by many orders of magnitude [3,4]. In this case, we obtained nanocomposites with multi-walled carbon nanotubes characterized by low percolation threshold values. This concentration behavior of the electrical conductivity of these nanocomposites is a consequence of the segregated nanotube distribution. On the other hand, the increase in electrical conductivity at concentrations above the percolation threshold is limited due to the high value of the contact resistance due to the adsorbed layers of polymer on the fillers [5-10].
