Abstract
The paper presents the results of studies on surface modification of finely dispersed tungsten (IV) dioxide with polyethylsiloxane from a solution of n-hexane with the aim of its compatibility and the possibility of uniform distribution in the volume of the nonpolar polyimide matrix. The energy dispersive interaction of the press powder of polyimide and highly dispersed modified WO2 in a jet-vortex mill allowed for the activation of their surface, as well as high uniformity of distribution of the filler in the polyimide matrix and excluded the possibility of the formation of agglomerates. It is shown that the use of modified WO2 increases the degree of filling of the polymer composite by 15-20% and the increase in the density of the composite by 16.0%.
