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 the last study, we were successfully synthesized the core-shell nanocomposites with a SWCNT in core and polypyrrole@PLLA shells with an average diameter of 60-80 nm via a simple one-port emulsion polymerization. The detection characteristics were observed in VOC gases such as ammonia and acetone at a concentration of 100 ppb even at room temperature. However, this material was not stable for humidity condition. Thus, in this study, we use C8F for SWCNT@PPY@PLLA nanorods to maintain detection properties of 100 ppb and to make materials stable material for humidity. |
