“…Practically total surface consists of comparatively shallow, but numerous (100 per 1 sq.micrometer) inclusions located perpendicular coating surface. Judging by the effective diameter of neoformations, comprising 10-20 nanometers, they are polarized elongated fragments of three-dimensional macromolecules of polymer structure with nanoscale titanium dioxide [19].…”

The paper considers the problems of creating new protective coatings based on organosilicon polymer – polymethylphenylsiloxane, modified with tetraisopropyltitanate. The mechanisms of siloxane polymer nanostructuring have been suggested. The coating surface nanostructure and the impact of material components content and nature on its properties have been studied. To research protective surface nanostructure, the method of atomic-force probe microscopy applying IntegraAura device has been used. Nanoparticles formations with 10-20 nm effective scale have been revealed. Adhesive properties of the protective coating have been studied. Glass and metal adhesion was determined applying the method of detachment from the steel discs substrate using adhesive meter PSO-MG4. The modification was stated not to cause any substantial loss of coating adhesive properties. Simultaneously modification process was accompanied with the increase of relative coating firmness.The developed compounds and corresponding coatings are aimed at protecting buildings and constructions against negative impact of natural and anthropogenic factors.

“…Nowadays, much attention is paid to organosilicon binders, including those with reactive hydroxyl groups, due to their high thermal stability and environmental safety, and the possibility of crosslinking at relatively low temperatures [11,12]. In previously published works [13][14][15][16], the physical-mechanical properties of syntactic foams based on organosilicon binders and hollow glass microspheres were considered. The aim of the present work is to study thermophysical characteristics of the developed construction materials.…”

The syntactic foams based on polymethylphenylsiloxane resin filled by hollow glass microspheres were developed for using in different applications of construction industry. Thermophysical properties of the developed syntactic foams were analyzed in this work. According to the study results, with an increase of polymethylphenylsiloxane content in the syntactic foam, the thermal conductivity and the specific heat capacity increased. The coefficient of thermal linear expansion was dependent on the ratio of the components, reaching the lowest value for the composites with a minimum binder content.

“…When developing protective coatings firstly it is necessary to take into account that most the polymeric materials produced on an industrial scale are not sufficiently resistant to atmospheric factors and mechanical impact. Polymer compositions, containing various reinforcing and stabilizing components, are usually used to increase polymeric material strength, hardness and stability, [1][2][3][4]. However, nanoscale components usage brings the best effect.…”

New materials based on oligooxidridsilmethylensiloxysilane nanostructured with ethyl ester of orthosilicic acid – tetraethoxysilane have been studied in the research. Tetraethoxysilane introduction into the composition is supposed to cause its decomposition up to nanoparticles of silicon oxide. The alkoxysilane hydrolytic destruction kinetics and the impact of the composition and nature of the polymer composition components on the physical properties have been studied. Atomic force microscopy was used to study the structurization kinetics of the polymer composition. The composition hydrophobicity was determined by the edge wetting angle. To study the adhesion characteristics of the obtained material, the method of disc separation from the substrate has been used. The relative rigidity has been determined by a pendulum device M3. Atomic force microscopy revealed the presence of nanoscale neoplasms (at average of one hundred twenty per one square micrometer) in diameter from two to five nanometers in the surface structure of the composition, modified with tetraethoxysilane. Herewith the physical properties of the material change: rigidity increases, the edge angle of wetting increases as well. The studied nanostructured compositions can also be applied. For example – they can be used as a protective coating with a set of special properties, such as high hydrophobicity.
