Flexible thin films based on Te-SnO2 nanocomposites and their gas sensing properties

Abstract

Printed electronics becomes very attractive due to the ability of using sustainable, compostable and recyclable materials including biobased plastics and paper in the elaboration of different flexible thin-film sensors, transistors and systems. In this talk I will present information related to development of flexible sensors based on printable Te-SnO2 nanocomposites for the detection of toxic and pollutant gases at room temperature. A brief review of fabrication, physical properties and application of both elemental tellurium and tin oxide in technology of the chemical sensors is reported and discussed in context of the development of the novel nanocomposites based on these very different semiconducting materials. Being sinthethized these nanocomposites appeared to be suitable for the application in printed electronics fo fabrication of flexible gas sensors, enabling low-cost fabrication through computer aided designs.
