Abstract

The paper reviews recent scientific developments at the Institute of Combustion Problems. The hydrophobic sponges were obtained by coating polyurethane and melamine sponges with carbon nanomaterials. They are excellent water-resistant sorbents for oil, petroleum products and other organic liquids of various densities. Another interesting development is concerned to the synthesis of multiwalled carbon nanotubes on a glass-cloth by use of cobalt oxide catalyst nanoparticles obtained by solution combustion and production of the smart-textile on its basis. A model of soldier with heated jacket based on electroconductive smart-textile was made. The textile showed good electroconductive properties and effective Joule heating by externally applied current. Studies on the development of nanostructured carbon materials and their application as high-performance active components for the electrodes of advanced energy storage systems, in particular electric double layer capacitors were carried out. 2D heterostructures based on graphene nd dichalcogenides of transition metals were derived. The epitaxial and single crystals of graphene were synthesized by the CVD-method separately on a copper foil. Two dimension WS2 layers were synthesized using sulfurization of thin WO3 films deposited by thermal evaporating on the FTO substrate. A setting time of concrete mass, which could be used as a construction material for 3D printing technology was determined. It was found that calcium chloride decreased the setting time up to 10 min, which is sufficient for the intended application.

Highlights

Nanotechnology is one of the most actively discussed directions of scientific and technological investigations which is being highly developed in the recent years and on which the hopes of a wide circle of scientists and technologies anchor their hopes

Summary

Introduction

Nanotechnology is one of the most actively discussed directions of scientific and technological investigations which is being highly developed in the recent years and on which the hopes of a wide circle of scientists and technologies anchor their hopes. This direction is considered as a basis of a new industrial revolution which must lead to the abundance of products principally new by their possibilities. Smart-textile was obtained by deposition/in situ synthesis of multiwall carbon nanotubes on glasscloth-based catalyst decorated with cobalt oxide nanoparticles obtained by solution combustion. It was stated that the development of methods for synthesis of individual 2D crystals and of heterostructures based on them is an important task in the field of 2D devices with the intended various applications [13,14,15]
