Apr 19, 2024 · Multifunctional microwave-absorbing (MA) honeycombs are in urgent demand both in civil and military fields, while they often suffer from great limitations due to the complicated preparation process, inferior strength, and the susceptible peeling off of the absorbent coatings. Herein, we develop a straightforward strategy of assembly of aramid nanofibers (ANFs) and MXene nanosheets to ...
Apr 23, 2024 · In this work, we obviously enhanced the mechanical and dielectric insulation properties of the aramid nanofiber (ANF) film only by mixing a small amount of two-dimensional boron nitride nanosheets (BNNSs) (0.09 wt %), which were in situ introduced as the assistor of aramid splitting. The composite nanofilm exhibited a tensile stress of 282 MPa and a dielectric breakdown strength of 100.7 kV ...
Apr 13, 2024 · The FTIR results show that the chemical structure of para-aramid is mostly preserved during this nanofiber deprotonation and reassembly process, while some slight upshift of C═O stretching from 1640 cm −1 (aramid fabric) to 1644 cm −1 (ANF film) and N–H stretching from 3315 cm −1 (aramid fabric) to 3320 cm −1 (ANF film) indicating a ...
2 days ago · Teijin Aramid is part of the Teijin Group, a global, technology-driven group operating in five main areas: synthetic fibers (polyester, carbon and aramid fibers); films and plastics; pharmaceuticals and medical appliances; wholesale and retail; and IT and new products.
Apr 23, 2024 · The Applications of silica aerogel are limited due to its brittleness and low strength. As a result, it is essential to strengthen and toughen it. Organic nanofibers are one of the preferred reinforcement materials. In this work, we designed and fabricated flexible and compressible nanostructure-assembled aramid nanofiber/silica composites aerogel (ANF/SiO2 aerogel) to improve the mechanical ...
Apr 25, 2024 · The aramid material combines high structural strength, heat resistance, and low density. When used as a coating, compared to traditional ceramic-coated separators, the coated film has a 50% reduction in surface density, a 60% increase in puncture strength, nearly 30% improvement in insulation, and the rupture temperature is also increased from ...
Apr 9, 2024 · Polymer nanofibers have established a robust foundation and possess immense potential in various emerging fields such as sensors and biotechnology. In this study, aqueous dispersions of aramid nanofibers (ANFs) were successfully prepared by using tannic acid (TA). Morphological analysis revealed that TA effectively prevented self-aggregation of ANFs, and preserved the nanofiber structure ...
