PROJECT TITLE :

CO2 Gas Sensors Based on Carbon Nanotube Thin Films Using a Simple Transfer Method on Flexible Substrate

ABSTRACT:

This paper presents a flexible carbon nanotube (CNT)-primarily based gas sensor on a coffee-value polyimide substrate that responds immediately to CO2 at space temperature. Highly uniform CNT thin films, ready by a reliable and reproducible transfer method, are used as resistive networks in gas detection. The versatile gas sensor exhibited a high sensitivity of 2.23p.c at space temperature when the concentration of ambient CO2 gas was 80zero ppm. Both the speed and the soundness of response of the fabricated sensor were favorable.
