Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Gas chemical nanosensors with sensitive elements based on polymers. Analysis of development during last years.Part 2 V.A. BUZANOVSKY Results of development of nanosensors sensitive elements of which have a multilayered covering based on polymer (devices of group 2) are submitted in the second part of the review. Among nanosensors of this group seven subgroups are defined. Subgroup 2.1 is devices with the sensitive elements containing a covering from a layer of polymer and an external layer of other material. Subgroup 2.2 is nanosensors sensitive elements of which have a covering from alternating layers of two polymers. Subgroup 2.3 is devices with the sensitive elements containing a covering from alternating layers of two polymers and an external layer of other polymer. Subgroup 2.4 is nanosensors sensitive elements of which have a covering from alternating layers of two polymers and external alternating layers of two polymers. Subgroup 2.5 is devices with the sensitive elements containing a covering from alternating layers of two polymers and external alternating layers of polymer and organic compound. Subgroup 2.6 is nanosensors sensitive elements of which have a covering from alternating layers of two polymers and external alternating layers of polymer and composite based on polymer. Subgroup 2.7 is devices with the sensitive elements containing a covering from alternating layers of two polymers, a layer of polymer and an external layer of metal. Analytical abilities of the listed nanosensor subgroups are considered. Key words: nanotechnology, nanomaterial, gas chemical nanosensor, sensitive element, covering, polymer, metrological characteristic. Contacts: Е-mail: vab1960@rambler.ru Pp. 51-57.
