Abstract The development of straightforward and dependable explosive sensors for on‐site identification is essential to preserving public safety concerns lowering the risks related explosions. However, one main barriers advancement explosives detection in future complexity process. Here, a flexible hydrogel‐based sensing platform based on 3,4‐bis (4‐(1,2,2‐triphenylvinyl) phenyl) thiophene (TPE‐Z) methyl red design concept shown that simultaneously achieves all targeted properties, including being quick, portable, reliable, resistant external interference. This composite fluorescent probe demonstrates outstanding capabilities, low limits (0.48 mg L −1 ) rapid response times (<5 s), which can be combined with smartphones 2,4,6‐trinitrophenol (picric acid, PA) detection. Two independent fluorescence colorimetric channels sensor showed selective PA under visible light irradiation, respectively. Meanwhile, hydrogel sensor's distinct “turn on” off” modes utilized construct “YES” “NO” logic gates, subsequently proves they employed differentiate on‐site. envisaged offer in‐depth insights advancing nitroaromatic explosives.

Recyclable Organic Ionic Conductive Hydrogels for Flexible Wearable Sensors with Excellent Environmental Resistance

ACS Applied Electronic Materials, Год журнала: 2024, Номер 6(9), С. 6626 - 6639

Опубликована: Авг. 24, 2024

Hydrogel sensors encounter limitations in practical applications due to factors such as a narrow operating temperature range, suboptimal mechanical properties, and limited recyclability. The development of hydrogel-based wearable that can effectively operate hot-wet or cold-dry environments remains significant challenge. In this study, the PVA@CNF-FeCl3-CNT (PCFC) hydrogel, based on poly(vinyl alcohol) (PVA) cellulose nanofibers (CNFs), was prepared using one-pot cyclic freeze–thaw process binary solvent system instead pure water. PCFC strain/pressure sensor exhibited remarkable characteristics including high sensitivity (S = 4.013% kPa–1 over pressure range 0–398 kPa), wide response (7615 exceptional durability (over 10,000 cycles), well short time (83 ms) recovery ms). It accurately detected various limb movements (e.g., finger flexion) physiological signals pulse) real-time at both low (−25 °C) temperatures (50 °C). Furthermore, organic hydrogels are fully reusable, owing their construction noncovalent interactions thermoplasticity. This work presents promising approach for utilizing hydrogel long-term devices extreme environments, while also addressing recycling waste materials.
