The recent advances of typical polyurethane (PU) porous sound absorption materials are reviewed in this work, including PU foam, modified PU porous materials, aerogel, templated PU, and special PU porous materials. Abstract Various acoustic materials are developed to resolve noise pollution problem in many industries. Especially, materials...

Abstract Stroke is the second result for death and ischemic stroke constitutes most of all stroke cases. Ischemic stroke takes place when blood clot or embolus blocks cerebral vessel and interrupts blood flow, which often leads to brain damage, permanent disability, or death. There is a 4.5-hour (golden hour) treatment window to restore blood flow...

Abstract This study investigates unexpected competitive host-guest interactions of β-cyclodextrin which can occur with polymers in aqueous solution, using the examples of the two polymers poly(oligo(ethylene glycol) methyl ether methacrylate) (POEGMA) and poly(glycerol mono methacrylate) (PGMA). Systematic structural modifications of the polymer provide...

Abstract The preparation of self-healing polyurethane elastomers (PUEs) incorporating dynamic bonds is of considerable practical significance. However, developing a PUE with outstanding mechanical properties and high self-healing efficiency poses a significant challenge. Herein, we have successfully developed a series of self-healing PUEs with various...

Abstract Electrochromic devices built with ionogel electrolytes are seen as a pivotal step towards the future of quasi-solid electrochromic devices, due to their striking properties like exceptional safety and high ionic conductivity. Yet, the poor mechanical strength of electrolyte of these devices remains a constraint that hampers their advancement....

Fully peptidic nanoparticles are obtained by a one-pot ring-opening polymerization-induced self-assembly (ROPISA) process in aqueous medium. Three types of peptidic materials, including a protein, are used to initiate the polymerization, and the intrinsic properties of the peptides are preserved on the surface of the nanoparticles, resulting in fully...
