The current state of the art in materials science of organosilicate composites

Abstract

Physicochemical regularities of processes occurring in the "polyorganosiloxane-silicate-metal oxide" system are investigated over a wide range of temperatures. The results of investigations are used to design organosilicate materials, such as heat-resistant functional coatings, high-temperature adhesives, and vacuum-tight sealants, which find wide application in various fields of engineering. Modern materials science of organosilicate composites is a dynamic knowledge system.

Changes in the energy characteristics of the surface of organosilicate coatings in the course of formation

“…The quantity can be determined from the known values of γ l v and according to expression (3). The measurements of the contact angles θ of to different liquids on the solid surface enable one to obtain pair equations for determining the components and .…”

“…Organosilicate coatings [1][2][3] possess quite different properties, such as the decorative, physicomechanical, and protective properties, the majority of which are manifestations of characteristics of a bulk (massive) material. In particular, the anticorrosive properties can be considered as a function of adhesive-cohesive interactions, permeability of the coating with respect to different reactants, and the glass transition temperature of the coating [4][5][6][7].…”

“…In the case of low-temperature curing, different curing agents are introduced into the composition of organosilicate suspensions [3,12,13]. The curing parameters affect the technological properties (the viscosity, durability, flow properties, drying time); hardness, adhesion, impact strength, flexural strength, and other physicomechanical properties; sol-gel fraction content; protective properties; heat resistance; and electrically insulating properties.…”

Anti-Icing gradient organosilicate coatings

“…Heat-resistant organosilicate coatings have been widely used over more than 50 years in various fields of engineering in our country and abroad as film materials that possess the unique functional characteristics [1][2][3][4][5][6]:…”

“…At temperatures below the destruction temperature of the organosilicon film former, the coating operates as a polymer material with a wide range of operating temperatures (as a rule, from -60 to +300 ° C). At temperatures above the destruction temperature, the organosilicate coating operates as a high-temperature inorganic coating that is formed through the interaction of products of thermooxidative destruction of the polymer with mineral components and through structural transformations in the material [4].…”
