Study of electrokinetic properties of nanoflllers used for the preparation of nanocomposites

摘要

The aim of the studies was to determine, how the zeta potential and particle size of nanofillers affect the stability of the dispersion of nanoparticles in the electroinsulating varnish, and consequently can influence the varnish properties. We have investigated the nanoflllers that had been used for the preparation of nanocomposites in our earlier works. It has been found that in toluene the zeta potential of all nanoflllers is much increased. It enables modifying of nanofillers. Correlation between the properties of the nanocomposite and the results of the particle size measurements has been observed. Thus studies of electrokinetic properties can be used during the preparation of nanocomposites, as well to determine the factors affecting the nanoparticles deagglomeration and a preliminary determination of the optimal technological parameters of process of preparing of nanocomposites.
