This study proposes a novel approach to address this issue by imparting self-healing functionality to commercial polyurethane without compromising its inherent mechanical strength. Ionic liquids were electrostatically adsorbed onto the surface of MXene quantum dots, triggering their reaction to form poly (ionic liquid)-coated MXene (MQDs@IL). These MQDs@IL were incorporated into commercial polyurethane, where hydrogen bonding interactions between the poly (ionic liquid) and the molecular chains in polyurethane, along with dynamically reversible ionic aggregates, facilitated molecular chain rearrangement. As a result, the modified polyurethane demonstrated an impressive self-healing efficiency of up to 80%. Additionally, the composite material exhibited enhanced mechanical properties, including increases in fracture strength and elongation at break by 9% and 14%, respectively, achieving a toughness of 294 MJ/m<sup>3</sup>.

The structure integrity and corrosion protective performance are greatly weakened by acid, high-pressure water and gas in the environment. Here, we prepared a novel reinforcement composite filler by bridging glass flakes (GF) and carbon nanotubes (CNT) with 3-aminopropyltriethoxysilane (APTES), and then introduced them into EP resin to obtain the superior coating named MGF@CNT/EP.

Remarkable synergism between ATH and MEG/MRP is found in CLEVA, which has increased flame-retardant efficiency significantly.

This article presents a stealth metasurface suitable for infrared, microwave, and terahertz frequencies.

This CSM uses the gradient principle to make absorption units of different sizes on its surface. To achieve cross-band absorption, it also uses a frequency-selective surface (FSS) as the reflecting layer, which is a first. Furthermore, the CSM's exterior is coated with low-IE materials, facilitating infrared stealth capabilities. The CSM's stealth properties across three electromagnetic wave bands make it very useful for military purposes, and the new way that FSS is used as a reflecting layer opens up a whole new way to make stealth metasurfaces that work with each other.</div></div>","PeriodicalId":10533,"journal":{"name":"Composites Communications","volume":"55 ","pages":"Article 102328"},"PeriodicalIF":6.5,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143521007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
