Conducting organic polymer gas sensors: correlating sensor responses with the nature of the sensor material.

Research output: Contribution to journalArticle


The study focuses on the polyalkylterthiophene group of conducting org. polymers (COPs) and studies the effect of varying polymer side chain and dopant ion on the elec. response of the materials to a variety of volatile org. chem. (VOC) classes. The broad conclusions of the study are that (a) the dominant factor affecting polyalkylterthiophene gas sensor response is the length of the polymer side chain, (b) dopant ions with high surface charge densities produce more sensitive gas sensors and (c) polar VOC classes are detected with greater sensitivity.
