Ethanol Gas Sensor Based on Self-Assembled Multi-Walled Carbon Nanotube Film

Abstract:

A multi-walled carbon nanotube (MWNT) film-based sensor was fabricated using layer-by-layer self-assembly method, and its ethanol gas-sensing properties with varying gas concentration are characterized at room temperature. The experiment results shown that the layer-by-layer self-assembled MWNT film sensor exhibit a fast response and linear resistance change when exposed to ethanol gas, indicated a prospective application for ethanol gas detection with high performance and low-cost.
