FIELD: chemistry.
SUBSTANCE: method involves preparing a nanosuspension by adding carbon nanotubes to a reactive plastic binder with ultrasonic exposure in a cavitation zone with intensity of 15-25 kW/m2. Carbon nanotubes are dispersed in the binder with simultaneous photographic recording of changes in colour intensity of the nanosuspension. When the nanosuspension reaches colour intensity values corresponding to standardised dispersion values in the range of 0.9 to 0.99, ultrasonic exposure is stopped.
EFFECT: method enables to optimise dispersion of carbon nanotubes in the binder and cut the duration of preparing high-strength nanocomposites owing to uniform distribution of nanoparticles in the nanocomposite.
