Investigation of Electrophysical Properties of Composite from Nano-Gel Film of Bacterial Cellulose with Addition of Carbon Nanotubes

Abstract-samples of composite material from nano-gel film of bacterial cellulose with addition of carbon nanotubes with concentration from 0.1% to 20% are made. The morphology of the obtained material is investigated. It is established that the electrical resistance of materials is a nonlinear function of the applied voltage. The resistivity of the resulting composite films was from 1 TΩ/m to 80 GΩ/m depending on the concentration of nanotubes; the breakdown field strength was from 18 kV/mm to 50 kV/mm. The factors influencing the accuracy of measurements of the parameters of the created composites are determined.
