Composites of carbon black functionalized with polymers as candidates for the detection of methanol vapor

Highly sensitive methanol chemical sensor based on undoped silver oxide nanoparticles prepared by a solution method

“…The high sensitivity of the fabricated NPs/GCE can be attributed to the excellent absorption (porous surfaces in NPs/binder/GCE) and adsorption ability, high catalyticdecomposition activity, and good biocompatibility of the NPs. The estimated sensitivity of the fabricated sensor is relatively higher and detection limit is comparatively lower than previously reported methanol sensors, based on other nano-composite or nano-materials modified electrodes [29][30][31][32][33][34]. Due to high specific surface area, the NPs provide a favorable micro-environment for the analyte detection with large quantity.…”

Ionic Liquid/Styrene-Acrylonitrile Copolymer Nanofibers as Chemiresistor for Alcohol Vapours

“…12 Good and efficient chemical vapour sensors require several fundamental preconditions: (1) high sensitivity and selectivity, (2) rapid response time and recovery time, (3) low analyst consumption, (4) low operating temperature and temperature independence, and (5) stability in performance. Therefore, many researchers have examined composites composed of conducting materials/polymers as candidates for chemical vapour sensors because composite materials have high sensitivity and reproducibility, good processability, and reasonable cost.…”

Structural effect of ferrocenecarboxymethylated polymers on their electrical behavior under the exposure to methanol and acetone vapors

“…1.62 × 10 5 ppm. The sensing properties of polymeric sensors that were exposed to methanol vapor at high concentration were also examined by Wang et al [11]. The composite of 6.90% carbon black grafted with poly(4-vinylpyridine) showed the sensitivity of ∼300% toward ∼1.1 × 10 5 ppm of methanol vapor, and the sen- 9.…”

“…The applications of conductive polypyrrole and polyaniline as gas sensors are mainly associated with the detection of volatile organic compounds, ammonia, chlorine, carbon dioxide [5][6][7], or initial fire smoke [8]. Previously, many researchers have utilized systems of polymer blends or polymer composites in obtaining the desired properties [9][10][11][12][13]. The common characteristic that is associated with the electrical conductivity of these CPs is the conjugation of double bonds along their main chains for electron movement [14,15].…”
