“…1,2 As vital application of wearable devices, electronic textile (e-textile) is used in human health care 3 or environmental monitoring. 4 One of the main applications of e-textiles is detecting hazardous gases, such as nitrogen dioxide (NO 2 ), 5 hydrogen sulfide, 6 ammonia, 7 formaldehyde, 8 hydrogen, 9 or sulfur dioxide. 4 Of these, NO 2 is the most toxic gas, causing not only environmental pollution, such as mild dust, acid rain, and destruction of the ozone layer but also detrimental effects on human health, such as mild irritation of the nose and throat, eye irritation, respiratory disease, nausea, and debilitating pulmonary system diseases.…”

Graphene-based e-textile gas sensors have received significant attention as wearable electronic devices for human healthcare and environmental monitoring. Theoretically, more the attached graphene on the devices, better is the gas-sensing performance. However, it has been hampered by poor adhesion between graphene and textile platforms. Meanwhile, amyloid nanofibrils are reputed for their ability to improve adhesion between materials, including between graphene and microorganisms. Despite that fact, there has been no attempt to apply amyloid nanofibrils to fabricate graphene-based e-textiles. By biomimicking the adhesion ability of amyloid nanofibrils, herein, we developed a graphene−amyloid nanofibril hybrid e-textile yarn (RGO/amyloid nanofibril/CY) for the detection of NO 2 . Compared to traditional e-textile yarn, the RGO/amyloid nanofibril/CY showed better performance in response time, sensing efficiency, sensitivity, and selectivity for NO 2 . Last, we suggested a practical use of RGO/ amyloid nanofibril/CY combined with a light-emitting diode as a wearable e-textile gas sensor.

A simple, cost‐effective, and novel chemical sensor for ammonia (NH3) gas detection was developed from polyaniline (PANI)/quail eggshell (QES) composites. QES is a natural waste enriched in calcium carbonate. In this work, pure PANI was synthesized from chemical oxidation method and PANI/QES composites were prepared from physical mixing of QES with the synthesized PANI at different mass ratio. A series of complementary techniques including Fourier transform infrared and ultraviolet‐visible spectrometers, scanning electron microscope with energy dispersive detection coupled with mapping, thermogravimetric analysis, and X‐ray diffractometer were used to characterize the physicochemical and textural properties of the biocomposites. From the results, PANI/QES composite with a mass ratio of 1 exhibited the lowest NH3 detection limit of 5.24 ppm with a linear correlation coefficient (R2) of close to unity (0.9932) between the signal and NH3 gas concentration. As a whole, the PANI/QES biocomposites synthesized from this work exhibited excellent selectivity toward NH3 gas even in the presence of other gas impurities, such as acetone, ethanol, and hexane. For the sensor reusability, the PANI/QES biocomposites can be reused in the application of NH3 gas detection for at least 4 cycles.

“…Thermal reduction of GO has demonstrated as an effective and green method and the annealing temperature is as low as 200 ℃ [22]. Conductive polymers have shown enormous potential in volatile organic compounds (VOCs) detection at room temperature as a result of their unique sensitivity, short response time and easy processing [23][24]. Polypyrrole (PPy) in particular has been widely used due to its outstanding chemical stability, redox properties, surface charge tunable characteristics, ease of chemical synthesis and light weight [25][26].…”
