Abstract
Uniform rough films containing up to 73 at % silver have been obtained by the Doctor Blade method from concentrated silver nanoparticle organosols stabilized with sodium bis(2-ethylhexyl) sulfosuccinate. Variations in the wettability of the films have been studied in detail as depending on the conditions of their heat treatment within a temperature range of 50–500°C. The temperature dependence of the contact angles is not monotonic and implies the transition from superhydrophilic to weakly hydrophilic systems due to the processes of sintering of nanoparticles and thermal decomposition of the stabilizer. It has been experimentally shown that a transition from nonconductive to conductive coatings (from 500 to 105 mΩ/sq) is accompanied by a drastic increase in the contact angle (from 25 to 78°).
期刊介绍：
Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
