Nanostructured Conducting Polymers for Sensor Development

Yen Wei, Meixiang Wan, Ten-Chin Wen, Tang-Kuei Chang, Caoquan Shi, 

The aim of this chapter is to provide a brief overview of various synthetical approaches to nanostructured conducting polymers and the development of these polymers for chemical and biological sensor applications. The references cited in this chapter are meant only to highlight specific aspects of conducting polymer nanostructures and their sensor applications. Some excellent books and reviews are available on more comprehensive descriptions of the fundamental aspects of conducting polymers and their nanostructures [3-5].

Although conducting polymers have received great attention in electronic or electrochemical devices for displays, energy storage devices, actuators, and sensors [3, 5], as mentioned above, the interchange rate is usually slow (i.e., a few

Three types of materials, metal oxide semiconductors such as ZnO and SnOa, conducting polymers such as polyanUine and polypyrrole, and carbon-based materials such as carbon nanotubes (CNTs) and graphene, have shown significant performance benefit for the development of 1-D- and 2-D-based sensors for VOCs (Table 14.3). Until recently, the development of 1-D nanostructure-based VOC sensor using the abovementioned materials was slow because of challenges in the synthesis and fabrication of these nanostructures with controlled dimensions, morphology, and purity.
