“…Hence, the hybridization of nanomaterials, besides improving the response rate, has also offered an opportunity to enhance the selectivity of the sensor towards a target gas. Reddy et al [21] fabricated a Sm 2 O 3 /rGO hybrid sensor on the flexible polyethylene terephthalate (PET) substrate for liquefied petroleum gas (LPG) detection. The Sm 2 O 3 /rGO (1, 3, and 5 wt %) hybrid sensors exhibited an enhancement in the response towards 10-1000 ppm of LPG as compared to Sm 2 O 3 sensor (Fig.…”

Owing to the unique properties such as pristine interfaces, ultra‐thin and uniform thickness, 2D nanomaterials have attracted the attention from many researchers. Particularly, rGO and MXene 2D nanomaterials have received intense research interest in the application of gas sensors due to their high electrical conductivity. The coating of these 2D nanomaterials onto plastic, paper or textile substrate formed flexible, stretchable and portable gas sensors as an alternative to the conventional rigid gas sensors. To date, numerous research works on flexible gas sensors using either graphene or MXene have been published. However, the reported data is scattered and varied by multiple factors. In this short review, we revisit the advances in the current application of 2D conductive nanomaterials (mainly rGO and MXene) and their nanocomposites with metal oxides on flexible gas sensors. We focus on recent developments regarding the working mechanism, advantages, disadvantages, and performances (including gas response, selectivity, response time, and recovery time) of each type of gas sensor. Finally, this short review sheds light on future directions and prospects in the field of flexible gas sensors using 2D nanomaterials.

In this paper, we report the liquefied petroleum gas (LPG) sensing behavior of polyaniline‐betel nut fiber (PANI/BNF) composite synthesized through a one‐step in situ oxidative polymerization method using HCl, H2SO4 and H3PO4 as doping acids. The deposition of emeraldine salt (ES) form of PANI on betel nut filament surface is explained by Fourier‐transform infrared spectroscopy (FT‐IR) and Ultraviolet–Visible (UV–vis) spectroscopy. Scanning electron microscopy (SEM) revealed that PANI particle size decreased and the thickness of the coated PANI layer increased with reaction time. Optical band gap of Polyaniline‐Betel nut fiber composites (PB) PB‐2, PB‐4 and PB‐6 were found be 3.68, 3.37, and 2.75 eV using the Tauc plot. X‐ray diffraction (XRD) analysis and thermogravimetric (TG) analysis showed that HCl‐doped PANI/BNF composites have high crystallinity and thermal stability as compared to the composites formed using H2SO4 and H3PO4. The electrical conductivity of the composites was determined by using a multimeter (Keithley Model 2000). The conducting filaments showed good resistive sensing activity toward LPG with minimum (100 ppm) 26% and maximum (1300 ppm) 44% of response sensitivity with decreasing response time and increasing recovery time. The plausible response mechanism of PANI/cellulose sensor toward LPG operating at room temperature is also discussed.
