The inventions in nanotechnologies as practical solutions. Part II

Abstract

A brief review of patents is given. The research performed by scientists, engineers and specialists in the area of nanotechnologies and nanomaterials result in increased efficiency of construction, housing sector and adjacent fields of economy. For example, invention «Elastic conductive film on the basis of silver nanoparticles», according to experts, is of great interest for science and industry. This new type of electronics potentially can be applied in many fields, such as elastic sensor skin for robot devices, portable electronics for functional clothes, elastic sensors and flexible electronic displays. Elasticity of materials is highly needed in electronic devices that contact the human body or curved surfaces. Elastic conductive film contains many annealed nanoparticles of conductive metal, in particular silver, applied on substrate. Adhesion of silver film is of great quality: when abrasion test was finished, there were no defects or there were slight defects.The specialists can also be interested in the following inventions in the area of nanotechnologies: a method to introduce single-wall and/or two-wall and/or multi-wall carbon nanotubes in composition of adhesive additives for asphalt coating and application of single-wall and/or two-wall and/or multi-wall carbon nanotubes in composition of adhesive additives; welding wire with nanocomposite coating for welding of high-tensile steel; A method to produce nanocomposite material based on aluminium; sewage treatment system with nanomodified natural sorbents et al.For citation: Ivanov L.A., Demenev A.V., Muminova S.R.

The effects of low curing temperature on the properties of cement mortars containing nanosilica

“…It can also be seen that the incorporation of nanosilica had a positive effect on the mechanical properties of cement mortars, by compacting their structure and improving the bond between the aggregate and the cement matrix. Various studies have shown that the incorporation of NS in a mixture accelerates cement hydration and composite hardening; resulting in higher early strength [7,19,24]. This was also reflected in this study, through the possibility of determining the 12-hour compressive strength of NS-modified specimens, after curing at 5 o C and 10 o C. Samples without the addition of nanosilica fell apart during the press test.…”

“…Recently, nanomaterials have received significant attention from researchers and industry, in regard to their potential as concrete admixtures [5]. This is evidenced by the rapid increase in the amount of patents as well as by the availability of the first commercial products using this technology [6,7]. Among nanomaterials, nanosilica has gathered particular attention.…”

Aryloxyphosphazene-Modified and Graphite-Filled Epoxy Compositions with Reduced Flammability and Electrically Conductive Properties

“…Carbon materials [4][5][6], nanofibers [7,8], nanotubes [9][10][11][12], nanoparticles of metal and metal oxides [13,14], graphene [15][16][17][18], and graphene oxide [19], as well as electrically conductive polymers (polyaniline, polypyrrole, and PEDOT:PSS) [20] and environmentally friendly ionic liquids, such as tributyl(octyl) phosphonium bis(trifloromethanesulfonyl) imide [21], can be used as conductive or antistatic agents to reduce the electrical resistance of materials. Carbon nanotubes and graphene have a conjugated structure in which carbon atoms are in the state of sp 2 hybridization, which makes it possible to transfer an electron along the entire carbon chain and conduct an electric current.…”
