제목 Synthesis and characteristics of SWCNT-polypyrrole core-shell nanorods for VOC gas sensor
초록 Conductive nano-carbon materials have shown great potential as gas sensor materials because they can be easily adjusted to detect various chemical compounds. In particular, the conductive polymers, such as polypyrrole and polyaniline, have the advantages of high sensitivity and fast response with selectivity for specific organic compounds, and as low-temperature reactants associated with organic conductors. In this work, we were successfully synthesized core-shell nano composites with a SWCNT in core and polypyrrole shells with an average diameter of 60-80 nm via a simple one-port emulsion polymerization. The obtained nanocomposites exhibited not only high conductivity but also high sensitivity to ammonia and acetone gas. Core-shell nanocomposite-based sensors showed a reliable detection at a concentration of 100 ppb even at room temperature and have the potential to be practically applied to gas sensors.
