CONTINUOUS METHOD ASSISTED BY ULTRASOUND WITH A VARIABLE AMPLITUDE AND FREQUENCY FOR THE PREPARATION OF NANOCOMPOUNDDS BASED ON POLYMERS AND NANOPARTICLES

摘要

The invention relates to a continuous mixing/extrusion method, assisted by ultrasound waves with a variable amplitude and frequency, for the preparation of nanocompounds based on polymers, preferably thermoplastics and nanoparticles, at a concentration of up to 60 wt.-% of the total weight of the polymer/nanoparticle mixture. According to the invention, the polymer/nanoparticle mixture is subjected in the molten state to a discrete and continuous sweep with a variable amplitude and frequency, of between 15 kHz and 5O kHz.
