“…Therefore, the emergency decontamination technology of CWAs has always been an important part of the public safety technology system [2]. Traditional CWA decontamination technologies, such as high-temperature incineration [3,4], hydrolysis [5,6] and chemical decontaminants [7,8], suffer from the problems of poor decontamination efficiency, complex operation procedures and serious environmental pollution. Therefore, it is necessary to explore a safe, efficient and green technology for CWA decontamination.…”

Low-temperature plasma is a green and high efficiency technology for chemical warfare agents (CWAs) decontamination. However, traditional plasma devices suffer from the problems of high power composition and large power supply size, which limit their practical applications. In this paper, a self-driven microplasma decontamination system induced by dielectric-dielectric rotary triboelectric nanogenerator (dd-rTENG) was innovatively proposed for the decontamination of CWAs simulants. Microplasma was characterized by electrical measurements, optical emission spectrum and ozone concentration detection. With output voltage of -3460 V, the dd-rTENG can successfully excite microplasma in air. The reactive species such as OH, O(1D), Hα, and O3 were detected. The decontamination rate of 2-chloroethyl ethyl sulfide (2-CEES) reached 100 % within 3 min plasma treatment. While the decontamination rate of malathion and dimethyl methylphosphonate (DMMP) reached 65.92 % and 60.88 % after 7 min plasma treatment, respectively. In addition, the decontamination rates gradually decreased with the increasing of simulants concentration. The typical products were identified and analyzed. This study demonstrates the broad-spectrum and feasibility of the dd-rTENG-microplasma for CWAs elimination, which provides significant guidance for their practical applications in the future.

“…It is necessary to develop CWAs detection technology with high sensitivity, good selectivity, strong anti-interference ability, fast response and compatibility with the current Internet of things technology. Nerve gases [ 2 ] are the most dangerous agents of chemical warfare and mass destruction, can cause irreversible damage to the nervous system within seconds and are fatal if exposure occurs for even a few minutes. Therefore, it is very dangerous for researchers to directly study such gases’ sensing characteristics in the laboratory.…”

In this paper, surface acoustic wave (SAW) sensors containing porous graphene/PVDF (polyvinylidene fluoride) molecularly imprinted sensitive membrane for DMMP gas detection were investigated. A 433 MHz ST-cut quartz SAW resonator was used to convert gas concentration changes into frequency shifts by the sensors. The porous graphene/PVDF film was fabricated on the sensor’s surface by using the tape-casting method. DMMP molecules were adsorbed on the porous structure sensing film prepared by the 2-step method to achieve the specific recognition effect. The sensitivity of the sensor could reach −1.407 kHz·ppm−1. The response time and recovery time of the SAW sensor with porous graphene/PVDF sensing membrane were about 4.5 s and 5.8 s at the concentration of 10 ppm, respectively. The sensor has good anti-interference ability to most gases in the air.
