Ambiently Dried Aerogel-Foam Composites with Gradient Pore Structure for Enhanced Sound Absorption

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: March 11, 2025

Silica-based aerogels are widely regarded as promising sound-absorbing materials due to their low density and high specific surface area. However, hard small pores hinder sound wave penetration, resulting in a relatively poor absorption performance. To overcome this limitation, our study employs melamine foam (MF) scaffold construct gradient aerogel composite acoustic absorber. This innovative design significantly leads average (31.3–117.4 mg/cm3) large up 13.7 mg/cm4 (approximately 2.7 times difference compared with the lowest density), its properties greatly improved, achieving an coefficient of 87% over entire frequency band 95% above 2000 Hz for 30 mm samples. In addition, best noise reduction can reach 0.59. For demonstration, simulations further reveal role pore size enhancing absorption. The skeleton facilitate coupling waves into structure, while effectively block transmission, providing additional pathways energy dissipation. Moreover, incorporation enhances foam's mechanical properties. terms thermal insulation, presence markedly improves insulating not only expands potential applications insulation but also provides novel approach development advanced materials.

Thermoresistive Network in Phase‐Transition Hydrogel: Achieving on/off Switchable Electromagnetic Interference Shielding

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

Published: April 4, 2025

Abstract Intelligent electromagnetic interference (EMI) shielding materials, with their tunable EM wave response characteristics, have attracted much attention. However, the molecular‐level mechanism is under‐explored and tuning range narrow. This study proposes an EMI switch hydrogel based on molecular precision manipulation of a thermoresistive network capable adaptively regulating performance. It has two temperature‐controlled switching states: on/off strong/weak shielding. The consists interpenetrating polyvinyl alcohol (PVA) poly(N‐isopropylacrylamide) (PNIPAM) networks, giving it thermal shrinkable properties.
