Abstract

Polyaniline nanotube was prepared with aid of lactic acid assembly. A chemical prototype sensor was constructed based on nanotube-structured polyaniline and two typical structured chemical sensors, one is an interdigital electrodes on flexible polymer substrate, the other is a highly sensitive quartz resonators. The gas-sensing behavior of the two typical sensors to some organic vapors operating at room temperature was investigated. Results showed rapid response, and good reversibility of these two typical sensors. The response time is 10-20 s, the reversible time is about 100 s. This study provides a simple approach for preparation of materials needed for a chemical sensor to selected organic volatiles with rapid response or organic flexible nanoelectronic devices.
