“…1e, the sensitivity increases with the higher concentration of iron ions, and the sensitivity also significantly improves with temperature elevation. The ionic liquid containing 400 mg mL −1 FeCl 3 exhibits an impressive sensitivity of up to 30.65%/°C, surpassing the reported values of traditional temperature-sensitive materials 16–36 (Fig. 1f) and much higher than that of PT100 (0.278%/°C), which is commonly used for high-precision temperature monitoring.…”

“…1 Therefore, developing temperature sensors with high precision and environmental adaptability remains a significant challenge. A variety of inorganic and organic temperature-sensitive conductive materials have been developed for resistive temperature sensors, including metals (gold, 16 silver, 17 and chromium 18 ), MXenes, 19 carbon materials (carbon nanotubes, 20 graphene, 21,23 graphite, 22 and carbon black nanoparticles 24 ), conductive polymers, 25,26 ionic hydrogels, 27–30 ionogels, 31–35 ionic liquids, 36 and commercial PT100. Among these materials, ionic liquids exhibit excellent potential for temperature-responsive applications.…”

“…Superhydrophobic materials are defined as materials that exhibit a water contact angle greater than 150° and a slip angle less than 10°. Surface roughness and low surface energy are considered the two primary factors contributing to the development of a superhydrophobic surface. – In this study, we investigated the influence of surface roughness on coating wettability by manipulating the surface morphology through adjustments in the mass ratio of SiO 2 and PTFE. We measured the contact angles (CAs) and slip angles (SAs) of water and cetane droplets on the coating.…”

In extreme environments, the simultaneous requirements of puncture resistance, acid and alkali resistance, and chemical corrosion resistance are crucial for the design of safety protection materials. To address these requirements, this study employed a "scratch coating" technique, combining modified silica nanoparticles (nano F−SiO 2 ) and thermoplastic polyurethane elastomers (TPU) with aramid fabrics. This approach ensured that the composites were both soft and puncture resistant. Additionally, a simple and cost-effective spraying method was utilized to create a multifunctional coating comprising nanosilica, micron-polytetrafluoroethylene (PTFE), and fluorinated alkyl silane. Furthermore, the study investigated the effect of different lamination angles of the fabric on puncture resistance. The results demonstrated that the soft composite exhibited outstanding puncture resistance, resistance to strong acids and bases, and super-double sparsity. Notably, the maximum puncture resistance reached 515.50 N, which was 33.02 times higher than that of the pure fabric (15.61 N). Similarly, the maximum knife puncture resistance reached 247.42 N, representing a 10.77-fold increase compared to that of the pure aramid fabric (22.97 N). Notably, the obtained coating demonstrated outstanding superhydrophobicity with a water contact angle of 163.8°and a sliding angle of 3.2°. It exhibited remarkable durability when immersed in acidic or basic solutions for 120 h and exposed to outdoor conditions for more than 30 days. Importantly, the micronano coating displayed exceptional stability even when subjected to highly corrosive chemicals such as concentrated sulfuric acid (98%) and sodium hydroxide (40%) for up to 12 h. In summary, this study introduces a novel approach and method for designing flexible puncture-resistant composites with multifunctional properties. It offers valuable insights and contributes to advancements in the field of protective materials..

Here, we demonstrate an improvement in sensitivity toward the NO2 analyte by varying the width ratio of adjacent graphene oxide (GO) and reduced graphene oxide (rGO) layers using the GO laser reduction technique. We evaluated changes brought by laser reduction in material morphology, structure, electrical characteristics, and sensing performance depending on the GO/rGO ratio, which we supported by density functional theory calculations. Our results indicate that the reduction of GO yields the appearance of a chemiresistive response to NO2. An optimum GO/rGO width ratio ensures high conductivity paired with good sorption capacity, allowing to achieve chemiresistive response of 18.1% toward 100 ppm of NO2 at 25 ± 1 °C and a limit of detection of 230 ppb. The improved chemiresistive response of GO/rGO sensors upon NO2 physisorption is due to an increase in sorption energy and improved charge transfer in the presence of NO2 at the sites corresponding to the individual epoxy and hydroxyl groups at the GO/rGO interface area when compared to fully reduced GO.
