ANFs were designed as an intermolecular cross-linker to reinforce MXene and the composite paper exhibited excellent EMI shielding performance with a multi-layered structure.
Lightweight, nanoporous aerogel fibers are crucial for personal thermal management and specialized heat protection. However, wet-spinning methods, exemplified by aramid aerogels, inevitably form a dense outer layer, significantly reducing the volume fraction of efficient barrier nanovoids limiting development ultimate resistance in fibers. Herein, we develop microfluidic spinning method to prepare gradient all-nanostructure (GAFs). Benefiting from simultaneous shear alignment diffusion...
Constructing mechanically strong and environmentally stable nanofluidic fibers with excellent ion transport remains a challenge. Herein, we design robust aramid nanofiber/carboxylated nanofiber (ANF/cANF) hybrid fiber high ionic conductivity via wet spinning-induced orientation strategy. Benefiting from the oriented structure interfacial interactions of filaments, ANF/cANF exhibits tensile strength 276.8 MPa. Carboxylation nanochannels dramatically reduce charge transfer resistance,...
Abstract The fabrication of mica‐based composites with good mechanical properties is very important especially for electrical insulation applications. In this study, a new aramid fibrid along chopped fibers was introduced into mica system, and the were prepared using papermaking machine. It found that both fibrid–mica composite (F‐M paper) fiber/fibrid–mica (A‐M largely improved in comparison reference sample (M an increase content or hybrid floc/fibrid. This enhancement can be attributed to...
Abstract Two‐dimensional nanofluidic membranes are promising candidates for various applications, such as energy conversion and ionic sensing. However, simultaneously achieving high stability ion transport in a membrane remains great challenge. Herein, robust durable aramid nanofiber/carboxylated nanofiber (ANF/cANF) hybrid is designed with conductivity selectivity via surface grafting engineering hybridization strategies. Due to the inherent ordered asymmetric molecular structure, strong...
An insulation network was constructed by adding hydroxyapatite nanowires (HNs) to a hydroxyethyl cellulose (HEC) system. The HNs improve the mechanical and insulating properties of composites. results showed formation strong chemical interactions between HEC HNs. Moreover, 20% addition maximized electrical tensile strength HEC/HNs film 12.7 kV/mm 34.12 MPa, respectively. Scanning electron microscopy revealed three-dimensional at perforated edge films, which prevented further decomposition...
Olefin block copolymer (OBC) is a novel thermoplastic elastomer possessing multiblock features but has limited mechanical property due to partial-branched hard segment. In this study, olefin was blended with linear polyethylene (PE) varying molecular chain lengths in order investigate the influence of on performance, crystallization behavior and crystalline morphology OBCs. It found that addition PE favor enhancing properties OBC. The long chains are more effective for reinforcing, thus...
Abstract Ionogels as ionic conductors have attracted extensive attention due to their excellent conductivity, good thermal and electrochemical stability, favorable non‐volatility compared conductive hydrogels. However, ionogels with conductivity usually suffer from low strength modulus. Herein, a facile yet effective strategy by compositing aligned cellulose fibers is presented achieve superior mechanical properties high conductivity. The triple hydrogen bond networks enable the possess...
