On the Electrical Conductivity, Microwave-Radiation Absorption, and Reflection of a Composite Based on Multi-Walled Carbon Nanotubes and Butadiene–Styrene Latex

The surface morphology, electrical conductivity, absorption and reflection of microwave radiation of a polymer composite with a concentration of multi-walled carbon nanotubes (MWCNTs) reaching 90 wt % are studied. Anomaly in the behavior of the electrical conductivity of the composite at the MWCNT concentration of 43–52% in butadiene–styrene latex is revealed, which correlates with the surface morphology, absorption and reflection of microwave radiation of the composite layers. A model to explain the obtained results is proposed.
