A Simple and Efficient Preparation Method for Flexible Pressure Sensors Using Salt Template and Vacuum Infiltration

Advanced Materials Technologies, Journal Year: 2025, Volume and Issue: unknown

Published: March 20, 2025

Abstract Flexible pressure sensor has a wide range of applications in physiological signal monitoring. Besides, flexible sensors with good properties like high sensitivity, flexibility, and excellent stability have become key direction for the research. In this paper, micro‐structured sponges (polydimethylsiloxane/carbon nanotube (PDMS/CNT)) is prepared using salt template, followed by application vacuum infiltration to introduce graphene nanoparticles (GNPs) into sponge skeleton. Surface microstructures are further created sandpaper enhance sensitivity. The not only achieves gauge factor (GF = 17.14) extremely low detection limits (4.5 mN) but also exhibits exceptional (over 3500 cycles at 5% strain, periodic signals do decay or show significant differences). addition, feature fast response (80 ms). proposed method features cost simple production processes, showcasing promise extensive potential intelligent healthcare across diverse areas.

Preparation of carbon foam from silicon‐containing polyarylacetylene/quartz powder with excellent oxidation resistance

International Journal of Applied Ceramic Technology, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 22, 2025

Abstract In this study, silicon‐containing polyarylacetylene (PSA) was used as a carbon source, and quartz powder (QP) filler to prepare PSA/QP composite foams through chemical foaming high‐temperature carbonization. The effects of the carbonization temperature QP doping on microstructure, apparent density, oxidation resistance were investigated. addition, PSA without prepared for comparison. results indicated that increased, pore sizes both decreased, while their densities increased. reduced degree shrinkage during carbonization, mitigated increase in promoted SiC formation, enhancing foams. At 1400°C, PSA/Q9‐1400 foam exhibited an density 0.273 g/cm 3 T d5 731°C, which can be long time atmosphere at 300°C. had low excellent resistance, makes them suitable thermal protection materials aerospace fields.

Comparative Study on the Foaming and Fireproof Properties of PDMS Foam Composites with Different Inorganic Fillers

Buildings, Journal Year: 2025, Volume and Issue: 15(7), P. 1172 - 1172

Published: April 3, 2025

In recent years, the increasing frequency of building fires has highlighted limitations traditional polymeric materials due to their inadequate fireproof performance. Ceramifiable polymer composites have emerged as a promising alternative by incorporating ceramic-forming fillers that create rigid ceramic-like structures through high-temperature eutectic reactions, offering exceptional thermal insulation and properties. These maintain structural integrity under fire exposure sufficient mechanical strength retention. The effects several ceramifiable inorganic (CIFs) on properties polydimethylsiloxane (PDMS) foams were systematically investigated in this study. research demonstrated with better matrix compatibility significantly enhance foaming quality, performance, capabilities. Notably, CaCO3-filled PDMS foam composite (CPF-Ca) demonstrates characteristics 84% porosity remarkably low density 0.36 g/cm3. material achieves tensile compressive strengths 0.22 MPa 0.84 MPa, representing 22% 127% enhancements, respectively, compared pure (PPF). Regarding ceramic conversion capability, sintered residue CPF-Ca maintains 4.39 conditions. This exhibited superior successfully withstanding butane torch for 300 s without penetration while maintaining backside temperature merely 83.6 °C.
