“…These detection units have the advantage of stand‐alone operation and low level detection, but they are very expensive, time consuming and too large in size to install on every emitting site. SO 2 is also detected by sensors based on electrochemical analysis, chemiresistors, potentiometric analysis, quartz crystal microbalance (QCM), surface acoustic waves (SAW) and field effect transistors (FET) . Electrochemical and potentiometric sensors have short lives, whereas SAW, QCM and FET based sensors are expensive or require special fabrication with sophisticated measuring equipment.…”

Among these, chemiresistors are the most promising entrants due to their low cost, good sensitivity, fast response/recovery time, simple electronic interface, and ease of use, low maintenance and good dynamic range.…”

We report the novel application of cetryltrimethylammonium bromide (CTAB) assisted polyaniline (PAN) nanostructures to fabricate cost effective chemiresistive sensors for monitoring a low parts per million level of sulfur dioxide (SO2) at room temperature. PAN nanoparticles (NPs, diameter ca 200 nm), nanofibres (NFs, diameter ca 100 nm) and nanoneedles (NNs, diameter ca 50 nm) were synthesized via template‐directed chemical oxidative polymerization of aniline by varying concentration of the solitary cationic surfactant CTAB (from 5 mmol L−1 to 15 mmol L−1). It was observed that the PAN NN based sensing device showed an excellent sensing response (ca 4.2%) towards a low concentration of SO2 (10 ppm) compared to the device based on PAN NFs (ca 3%) and PAN NPs (ca 1.2%) at room temperature. The PAN NN based sensing device was also found to be efficient in terms of stability, selectivity, reproducibility, recovery and response time, and detection range. The mechanism of SO2 sensing has been explored for the first time by using in situ Fourier transform infrared spectroscopy. © 2015 Society of Chemical Industry

A fabrication method about single-walled carbon nanotube (SWCNT) network and polydimethylsiloxane (PDMS) based composite thin film is reported, which can be used as flow sensor cell. This composite thin film is immersed in deionized water and salt solution with different flow rate tests. The morphology of SWCNTs on the surface of the composite thin film is characterized by scanning electron microscopy, revealing the SWCNTs are coated by PDMS chains. The induced voltage generates along the direction of the flowing liquid and depends significantly on the ionic concentration and flow velocity. Since the SWCNTs are fixed into PDMS matrix, the I-V curves of the composite thin film before and after several flow velocity measurements are exactly coincident, and the repeating flow-induced voltage experiment shows the composite thin film has a reliable electric characteristic and wide potential of device application.
