PEDOT:PSS/MWCNTsCOOH/PVP and PEDOT:PSS/PVP nanofibers were successfully fabricated by electrospinning in order to use as a chemiresistor for detecting the aromatic volatile organic compounds (VOCs) for the first time. The response magnitudes and the cyclic tests of electrospun PEDOT:PSS/MWCNTsCOOH/PVP and PEDOT:PSS/PVP nanofibers to benzene, toluene, and o-xylene vapors were investigated. It was found that electrospun PEDOT:PSS/MWCNTsCOOH/PVP nanofibers showed much enhanced response magnitude than that of electrospun PEDOT:PSS/PVP nanofibers to benzene, toluene, and o-xylene, respectively. Also, electrospun PEDOT:PSS/MWCNTsCOOH/PVP and PEDOT:PSS/PVP nanofibers displayed reversible and reproducible responses to benzene vapor at room temperature.
Graphical abstractElectrospun PEDOT:PSS/carbon nanotubes/PVP nanofibers as chemiresistors was fabricated and used to investigate the sensing properties for aromatic volatile organic compound (VOC) vapors such as benzene, toluene, and o-xylene.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► PEDOT:PSS/carbon nanotubes/PVP nanofibers were prepared by electrospinning. ► Carbon nanotubes were well-incorporated in the nanofibers. ► The PEDOT:PSS/carbon nanotubes/PVP nanofibers were used as chemiresistor for aromatic volatile organic compounds (VOCs). ► The nanofibers chemiresistor exhibited stable and fast response at room temperature.
