Abstract Flexible sensors based on MXene-polymer composites are highly prospective for next-generation wearable electronics used in human–machine interfaces. One of the motivating factors behind progress flexible is steady arrival new conductive materials. MXenes, a family 2D nanomaterials, have been drawing attention since last decade due to their high electronic conductivity, processability, mechanical robustness and chemical tunability. In this review, we encompass fabrication MXene-based polymeric nanocomposites, structure–property relationship, applications sensor domain. Moreover, our discussion not only limited design, mechanism, various modes sensing platform, but also future perspective market throughout world. With article, intend fortify bond between matrices MXenes thus promoting swift advancement MXene-sensors technologies.

While the majority of reports on toluene gas sensors are rigid electrodes and based composite materials, doping with additional noble metals, or a high temperature detection method, this work is first demonstration vanadium carbide (V2C) MXene flexible room-temperature (RT) sensor. The V2C synthesized by an HF etching route. field emission scanning electron microscopy (FESEM) transmission (TEM) images exhibit typical accordion-like multilayered structure MXene, where Fourier-transform infrared spectroscopy (FTIR), Raman, X-ray photoelectron (XPS) data further ensured its successful growth. (band gap 3.9 eV) sensor employing polyester substrate, displays good reproducibility, quick response/recovery time (14 s/34 s), long-term stability, cross-selectivity, low limit 47.85 ppb over linear region 5–200 ppm at RT (27 ± 1 °C). effect relative humidity (RH) toward sensing has also been investigated here. This shows excellent response 775% 200 toluene, brilliant selectivity six other hazardous gases. sensor's plentiful surface functional groups (−F, −OH, −O) superior electrical characteristics responsible for enhanced performance. In light this, can be smart way to fabricate next-generation sensors.

ACS Applied Materials & Interfaces, Год журнала: 2024, Номер 16(7), С. 9126 - 9136

Опубликована: Фев. 7, 2024

Gas sensors for acetone detection have received considerable attention because has a significant influence on both the environment and human health, e.g., it is flammable toxic may be related to blood glucose levels. However, achieving high sensitivity selectivity at low concentrations still great challenge date. Here, we report unique chemiresistive gas sensor detection, which composed of In2O3 nanofibers loaded with porous Co-based zeolitic imidazolate framework (ZIF-67)-derived Co3O4 cage prepared by simple electrospinning solvothermal methods. The ZIF-67-derived oxide cage/nanofiber Co3O4/In2O3 heterostructure abundant reversible active adsorption/reaction sites type-I heterojunction, resulting in an ultrasensitive response 954–50 ppm 300 °C. In addition, demonstrates limit 18.8 ppb, fast time 4 s, good repeatability, acceptable humidity interference, long-term stability. With such excellent sensing performance acetone, our could potentially applied environmental monitoring early diagnosis diabetes.
