Extended Abstract: The inventions in the area of nanotechnologies and nanomaterials produce

a profound effect in construction, housing and communal services and adjacent economic fields. The invention «The method to produce foamed polyurethane nanocomposite (RU 2566149)» refers to production of constructional materials, in particular to polymer composites, that includes polymer and inorganic additive. Constructional materials based on foamed polyurethane is of great interest for many areas of industrial and power engineering as well as for shipbuilding, airplane engineering and car industry; this interest is due to the fact that such materials possess high heat-insulating properties, considerable chemical resistance respect to environment (atmosphere and sometimes water) as well as good soundinsulating characteristics. The use of the materials makes it possible to provide an efficient thermal protection required in structures. The method to produce foamed polyurethane nanocomposite includes preliminary mechanical activation of the modifier with the following introduction of it into hydroxyl-containing polyester under ultrasound in the quantity of 0,5–3,0% respect to the weight of the produced nanocomposite, mixing and introduction of hardening agent. The invention «The method to produce complex nanodispersed additive for high-strength concrete (RU 2563264)» refers to construction and building materials industry, in

particular to the methods of production of complex nanodispersed additives. In this method the suspension with solid phase concentration 3% is produced by means of ultrasound dispersion when frequency of the ultrasound is 35 kHz. The suspension contains 65–70 mas.% of mineral element – metakaolin, 30–35 mas.% of super plasticizer C-3 in the form of dry substance and water. The technical result is the decreased particle size, decreased time of ultrasound impact and simpler additive production technology.

The specialists may be also interested in the following nanotechnological inventions: the method to produce nanocrystal highly refined cellulose (RU 2550397); the method to form stable nanostructural coatings with plasma stream (RU 2567082); the method to produce articles from glass (RU 2567062); the method to produce diamond-containing composition (RU 2567058); the method to produce short carbon nanofibers, catalyst to perform the method and the method to produce catalyst (RU 2566781); the modified polyester composition and the method to produce it (RU 2566756); the method to produce zirconium carbide (RU 2566420) etc.

Key words: nanocomposite, nanomodifier, nanodisperse additive, nanotechnologies,

nanostructured carbon coating, nanogels, nanospores.
