Abstract
Filled fractal aluminosilicates have been synthesized by a sol-gel method. Optimal conditions to obtain aluminosilicate gels have been determined. The obtained samples have been studied by IR spectroscopy, X-ray phase analysis, transmission electron microscopy, and the du Nouy method. The studies have shown the presence of chemically unbound –OH groups in the aluminosilicates. The effect of the amount of polymer matrix filled with highly dispersed filler powder and medium acidity on the adhesive strength of the dielectric layers applied on aluminum bases by 3D aerosol printing used in printed circuit boards of power electronic spacecraft devices has been studied by means of the du Nouy method.
