Electric Conductivity, Absorption and Reflection of Microwave Radiation of a Polymer Composite Based on Multi-Walled Carbon Nanotubes
The results of studying the surface morphology, electrical conductivity, absorption and reflection of microwave radiation of a polymer composite with a concentration of of multi-walled carbon nanotubes up to 90% are presented. An anomaly was found in the behavior of the electrical conductivity of the composite at a concentration of multi-walled carbon nanotubes of 42–52% in the styrene-butadiene latex polymer, which correlates with the surface morphology, absorption and reflection of microwave radiation of the composite layers. A model is proposed that explains the results of the study. It is found that the investigated composite with an 80–90% content of multi-walled carbon nanotubes can be used as radioprotective coatings.
