The mechanism of the influence of ultrasound (US) field on conductive properties of filled polymeric materials based on poly(dimethylmethylsiloxan) and polypropylene was investigated at room temperature and above up to 80°C. It has been shown, that the effect of US on the conductivity of composites essentially depends on such factors as density of crosslinked bonds, concentration and type of fillers, degree of crystallinity and interaction between polymer and filler. It is found that composites conductivity decreases as US power increases because of the increase in intensivity of Brownian motion of filler particles. This motion is connected with segmental movement of macromolecules which essentially depends on the character of macromolecular microstructure and the value of interaction between composites components. |
