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

Research output: Contribution to journalArticle

Abstract

The study focuses on the polyalkylterthiophene group of conducting organic polymers (COPs) and investigates the effect of varying polymer side chain and dopant ion on the electrical response of the materials to a variety of volatile organic chemical (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.
