- Abstract
Methods of macroelectrophoresis, spectrophotometry and electronic microscopy were applied for investigation of the silver hydrosols characterized by electrostatic factor of stability. It has been shown that the preparation of aggregative stable sols with increasing of reagents’concentration is limited not only by screening of the electrical double layer but also by decreasing of the surface potential. The proposed procedure allows applying the electrostatic stabilized silver sols for the preparation of composites with fractal aggregates of nanoparticles - new photochromic materials.
