“…Graphenepolypyrrole composites prepared by oxidative polymerization technique are used for supercapacitor and Hg 2+ removal applications, respectively [14,15]. Different graphitic materials, viz., graphite, graphite oxide and reduced graphene oxide are polymerized with polypyrrole by using in-situ polymerization method and later spin-coated on silicon substrate for ammonia sensing applications by Jang et al [16]. PPy-rGO composite is prepared by redox reaction under UV illumination and later sprayed on finger coated electrodes for NO 2 gas sensing application [17].…”

“…The superior performance of the composite aerogel along with simple and low-cost fabrication process could be employed for developing highly sensitive and economically feasible gas sensors. In another similar work, the unique electrical properties of rGO and PPy were combined for NH3 gas sensing application in which the performance comparison of rGO/PPy nanocomposite with intrinsic graphitic materials and nanocomposites of GO, graphene and graphite with PPy have been discussed [139]. The effective electron charge transfer between PPy and NH3 and the efficient transfer of resistance variation in PPy by the uniformly dispersed rGO in the rGO/PPy nanocomposite enabled rapid and highly sensitive detection of ammonia gas, compared to PPy/GO, PPy/graphene, PPy/graphite and graphite.…”

Two-dimensional materials have attracted great scientific attention due to their unusual and fascinating properties for use in electronics, spintronics, photovoltaics, medicine, composites, etc. Graphene, transition metal dichalcogenides such as MoS2, phosphorene, etc., which belong to the family of two-dimensional materials, have shown great promise for gas sensing applications due to their high surface-to-volume ratio, low noise and sensitivity of electronic properties to the changes in the surroundings. Two-dimensional nanostructured semiconducting metal oxide based gas sensors have also been recognized as successful gas detection devices. This review aims to provide the latest advancements in the field of gas sensors based on various two-dimensional materials with the main focus on sensor performance metrics such as sensitivity, specificity, detection limit, response time, and reversibility. Both experimental and theoretical studies on the gas sensing properties of graphene and other two-dimensional materials beyond graphene are also discussed. The article concludes with the current challenges and future prospects for two-dimensional materials in gas sensor applications. OPEN ACCESSElectronics 2015, 4 652

“…The values of the saturated vapor pressure were obtained from Lange's handbook of chemistry by John A. Dean, Fifteenth Edition, Mc Graw-Hill, Inc. [27].Taking into account of some other ammoniasensing composite materials like Polypyrrole graphitic nanocomposite [28], Polypyrrole/Metal Sulphide nanocomposite [29], poly(3-methythiophene)-titanium(IV) molybdophosphate cation exchange nanocomposite [6] and polyaniline-titanium(IV) phosphate cation exchange nanocomposite [8] reported earlier and compared with PPy-ZrP for ammonia sensing, the following observation can be noted (Fig. 10).…”

Electrically conductive polypyrrole-zirconium(IV) phosphate (PPy-ZrP) cation exchange nanocomposites have been synthesized for the first time by in situ chemical oxidative polymerization of pyrrole in the presence of zirconium(IV) phosphate (ZrP). Fourier Transform Infra-red spectroscopy (FTIR), field emission scanning electron microscopy, transmission electron microscopy, X-ray diffraction, thermogravimetric analysis, differential thermal analysis, derivative thermogravimetry and elemental analysis were used to characterize PPy-ZrP cation exchange nanocomposite. The composite showed good ion-exchange capacity (1.60 meq g -1 ), DC electrical conductivity (0.33 S cm -1 ) and isothermal stability in terms of DC electrical conductivity retention under ambient condition up to 100°C. PPy-ZrP cation exchangenanocomposite-based sensor was fabricated for the detection of ammonia vapours of aqueous ammonia. The resistivity of the nanocomposites increases on exposure to high-concentration ammonia vapours at room temperature (25°C). The rate of reaction for ammonia vapour-sensing on PPy-ZrP was observed as second order.
