▎ 摘　　要

NOVELTY - Inventions group relates to the field of sensor technology and nanotechnologies, in particular to the manufacture of gas sensors and chemoresistive type gas analytical multisensor lines. The design of the gas sensor includes a dielectric substrate, coplanar strip electrodes located on the substrate, thermistors, heaters, and a gas-sensitive layer divided into two or more segments, each of which is formed on the basis of graphene materials of different chemical composition, which at room or elevated temperature resistance changes under the influence of impurities of organic vapors or water vapor in the surrounding air. Graphene derivatives, which are graphene covalently modified with oxygen-, nitrogen-, sulfur- or halogen-containing functional groups at a concentration of at least 4 at.%, as well as the mentioned graphene derivatives modified with metal oxide nanoparticles (MeOx, where Me is a metal, x=1 or 2), such as zinc oxide (ZnO), tin dioxide (SnO2), titanium dioxide (TiO2), cerium oxide (CeO) or copper oxide (CuO), with particle sizes from 10 to 20 nm and the distance between individual nanoparticles or their clusters is not less than 5 nm and not more than 50 nm. In this case, the segments of the gas-sensitive layer are made with different thicknesses from 5 to 800 nm. A method for manufacturing said gas sensor is also provided. USE - Sensor technology and nanotechnologies. ADVANTAGE - Invention provides increased gas sensitivity and efficiency of selective gas detection. 15 cl, 55 dwg
