Effect of physicochemical factors on the distribution of high-dispersion metallic particles in an epoxy matrix

Abstract

Examination of the distribution of particles of high-dispersion nickel in a polyimide matrix [2] showed that the forces of magnetic attraction between the particles affect the correlation in the distribution of associates and their size distribution. Using the data and method described in [2], the aim of this work was examine the nature of distribution, in a polymer matrix, of particles of high-dispersion iron with magnetic moments almost an order of magnitude higher than the magnetic moments of nickel particles, and of particles of high-dispersion copper for which the contribution of the forces of magnetic attraction is insignificant. In addition, investigations were carried out into the effect of the nature of modification of the surface of particles of high-dispersion iron on the relationships governing their distribution in the matrix because the variation of the activity of the filler, including metallic filler, by modifying its surface with lowand high molecular compound, as well as the formation of transition polymer layers at the interphase boundaries are efficient methods of controlling the structure formation processes in the composites [3].
