“…For acetic acid at levels of 100, 200 and 500 ppm, the response values are about 23, 112 and 153, the response time is 18, 15 and 9 s, and the recovery time is 11, 10 and 10 s, respectively. As shown in Table 2, the gas-sensing response, optimal operating temperature and response-recovery time of our products are all better than some papers reported before [39][40][41][42]. It can be seen from which that the as-prepared flower-like nanostructures enhance the response vastly.…”

“…Till now, few studies have been carried out regarding the acetic acid sensing characteristics of ZnO nanoparticles. Some sensors utilize doped semiconducting metal oxide nanolayers, with detection based on resistance measurements [6,7]. The principle of action of such sensors is based on the catalytic degradation of acetic acid on the doped metal nanostructured surface.…”

“…Particularly, the resistance of metal oxide based sensors for acetic acid at 120-400°C depends on the type of metal oxide and the doping. In particular, a correlation between concentration of acetic acid and variation in measured resistance of the sensor has emerged [6,7]. Therefore, novel analytical and/or bioanalytical methods, which overcome current state-of-the-art and enable fast, sensitive, specific and high-throughput detection, are in great demand.…”

“…The photoluminescence of ZnO is very attractive for sensor development operating at room temperature because, once properly functionalized, ZnO can be exploited as a selective analytical transducer, which enables to enhance the analytical signal, increase detection sensitivity and signal-to-noise ratio [3][4][5][6][7][8].…”

In this study, we report a novel ZnO/polyaniline (PANI) nanocomposite optical gas sensor for the determination of acetic acid at room temperatures. ZnO nanorods, synthesized in powder form were coated by PANI (ZnO/ PANI) by chemical polymerization method. The obtained nanocomposites were deposited on glass substrate and dried overnight at room temperature. Structure and optical properties of ZnO/PANI nanocomposite have been studied by using X-ray diffraction, transmission electron microscopy, scanning electron microscopy, diffuse reflectance and photoluminescence spectroscopy. Tests towards acetic acids were performed in the range of concentrations 1-13 ppm. The adsorption of acetic acid on the sensor's surface resulted in the decrease of ZnO/ PANI photoluminescence. The response and recovery time of the sensor were in the range of 30-50 s and 5 min, respectively. The developed sensors showed sensitivity towards acetic acid in a range of 1-10 ppm with the limit of detection of 1.2 ppm. Specially designed miniaturized sensing system based on integrated sensing layer, light emission diode as excitation source and optical fiber spectrometer was developed for the measurement of the sensor signal. The developed sensing system was applied for the investigation of some real sample assessment including the evaluation of storage conditions of ancient cellulose acetate films, which during the degradation are releasing acetic acid. The obtained results suggest that the developed novel optical ZnO/PANI nanocompsite based sensor shows great potential for acetic acid determination in various samples.
