EFFECT OF ULTRASONIC TREATMENT OF AQUEOUS POLYVINYL ALCOHOL–CARBON NANOTUBE SUSPENSIONS ON THE ELECTRICAL CONDUCTIVITY OF POLYMER-CARBON COMPOSITE FILMS OBTAINED BY THE SPIN-COATING METHOD

Abstract—The article presents data on the cavitation homogenization of aqueous suspensions of polyvinyl alcohol and carbon nanotubes and its effect on the homogeneity and electrical conductivity of polymer layer composites formed by the spin-coating method using these suspensions. It is shown that the fundamental possibility of obtaining an effective composite material in the polyvinyl alcohol–carbon nanotube system to form homogeneous planar electrodes with a specific conductivity of up to 9 Ω–1 cm–1.
