Published: March 14, 2025

Producing thermoplastic room temperature phosphorescent (RTP) materials with closed-loop recyclability from natural sources is an attractive approach but hard to achieve. Here, the study develops such RTP materials, Poly(TA)/Cell, by thermally polymerizing thioctic acid in presence of cellulose. Specifically, polymerized poly(TA) forms strong hydrogen bonding interactions CNF, promoting formation molecular clusters between oxygen-containing units. The as-formed generate humidity- and excitation-sensitive green emission. Red afterglow emission also obtained integrating Poly(TA)/Cell together Rhodamine B (RhB) via energy transfer process. Attributed properties, as-obtained can be molded into flexible shapes uncompromised performance. Moreover, owing alkali-cleavable properties disulfide bond cellulose successfully recycled a yield 92.3% 81.5%, respectively. As demonstrator for potential utility, used fabricate information encryption.

Boosting Sensitivity of Cellulose Pressure Sensor via Hierarchically Porous Structure

Nano-Micro Letters, Journal Year: 2025, Volume and Issue: 17(1)

Published: March 31, 2025

Abstract Pressure sensors are essential for a wide range of applications, including health monitoring, industrial diagnostics, etc. However, achieving both high sensitivity and mechanical ability to withstand pressure in single material remains significant challenge. This study introduces high-performance cellulose hydrogel inspired by the biomimetic layered porous structure human skin. The features novel design composed soft layer with large macropores hard small micropores, each which contribute uniquely its pressure-sensing capabilities. part facilitate deformation charge accumulation, providing exceptional low pressures. In contrast, microporous enhances range, ensuring support under pressures preventing structural failure. performance is further optimized through ion introduction, improves conductivity, as well sensitivity. sensor demonstrated 1622 kPa −1 , detection up 160 kPa, excellent conductivity 4.01 S m rapid response time 33 ms, limit 1.6 Pa, outperforming most existing cellulose-based sensors. innovative hierarchically architecture not only but also offers simple effective approach utilizing natural polymers sensing technologies. demonstrates potential monitoring sensitive, durable, versatile solution sensing.
