Abstract
Abstract In this work, we reported a gradient structure that can significantly improve the mechanical strength of aramid paper by depositing a layer of nano-aramid fibers (ANFs) on both sides. The introduction of Dimethyl Diallyl Ammonium Chloride (DMDAAC) in the fabrication of nanostructured aramid-composites dramatically promotes the dewatering efficiency of the aramid nanofibers slurry, and also accelerates the formation of gradient structural of the composites. The gradient deposition of ANFs in the porous aramid paper matrix yields the highly pilotaxitic textures and stiff structures of the aramid composite paper. The results indicated that the tensile strength, specific strength, and fracture energy increased respectively 36.7 times, 14.1 times and 78.0 times from the original aramid paper. The method reported in this work gives a good case for designing the structure composites with low density and high strength in aerospace and car manufacturing applications.

Abstract The selective fluorination of aramid fiber surface was reported by Fe3+ coordination on the benzimidazole unit. After the coordination, both of the two parts in benzimidazole unit, benzene ring and imidazole ring, take priority in the reaction with the fluorine gas, while the reaction with the amide bond is restrained. In this way, selective fluorination on benzimidazole unit is achieved, with the surface polarity increasing and chain scission behavior suppressed simultaneously. What鈥檚 ...

Abstract The weak interfacial adhesion of aramid fiber with resin matrix is believed as a major limitation for its wide application. In this study, a nondestructive grafting method was applied for surface modification of benzimidazole-contained aramid fiber. Using the NH in benzimidazole unit as active sites, aramid fiber surface was firstly decorated with densely SiO2 structure, and a rough surface was obtained. Then, high density of NH2 and C=C groups were introduced on fiber surface by the re...

Aramid fiber-based composite paper is widely used as an engineering material that is often used in outdoor environments. This inevitably cause ultraviolet (UV) damage to aramid fibers. In this work, nanotitanium dioxide (nano-TiO2) was introduced to endow the composite a good UV-resistance while nanofibrillated cellulose (NFC) was used to disperse and deposit TiO2 nanoparticles onto aramid fibers by physical interaction. Firstly, TiO2 nanoparticles were treated by (纬-aminopropyl) triethoxysilane...

A general and scalable strategy to achieve transparent and hazy cellulose films with excellent mechanical properties, especially folding endurance, remains an obstacle. Herein, we incorporate transparent carboxymethyl cellulose (CMC) into opaque but hazy paper of uniformly distributed lignocellulosic fiber network by a facile and scalable impregnation to fabricate transparent and hazy all-cellulose composite films with strong mechanical properties. The CMC serves as a matrix to enhance the trans...

Abstract The poor Uv stability and weak interfacial adhesion are considered as the bottleneck problems for further application of aramid fiber. Herein, a new strategy, Fe 3+ coordination, was reported for aramid fiber to simultaneous improve its Uv resistance and composite interfacial shear strength. Fe 3+ was introduced onto aramid fiber by coordinating with benzimidazole unit of fiber structure. It can reach a doping capacity of as high as 1516ug/g fiber, and the fiber surface is saturatedly c...

AbstractDomestic Aramid Fiber III (DAF III) was modified by oxygen plasma treatment. The effects of oxygen plasma treatment power on fiber surface and DAF III reinforced bismaleimides (BMI) composite interfacial properties were investigated, respectively. The fiber surface characteristics were analyzed by X-ray photoelectron spectroscopy, Scanning Electron Microscopy, Atomic Force Microscopy and Dynamic Contact Angles Analysis, respectively. The results showed that oxygen plasma treatment introd...

Biodegradable highly nanostructured paper has received great interest in past years due to its excellent optical properties which facilitate its wide applications in green flexible electronics and devices. However, energy and/or time-consuming procedure during the process of fabricating most nanostructured transparent paper are presently the main obstacle to their scalable production. In this work, we demonstrated a novel nanostructured paper with dually high transparency (鈭91%) and high haze (鈭...

Structural energy and power systems offer both mechanical and electrochemical performance in a single multifunctional platform. These are of growing interest because they potentially offer reduction in mass and/or volume for aircraft, satellites, and ground transportation. To this end, flexible graphene-based supercapacitors have attracted much attention due to their extraordinary mechanical and electrical properties, yet they suffer from poor strength. This problem may be exacerbated with the i...

Abstract It remains challengeable for fabricating polymer nanocomposites with combined high strength and toughness. Inspired by spider silk with multiscale hierarchical architectures, we used aramid nanofibers F-3 (ANFs-3) to reinforce poly (vinyl alcohol) (PVA) via hydrogen bonding assembly. The PVA/ANFs nanocomposite films were prepared by a simple solution casting method. Our results showed that the simultaneously significant enhancement in both strength and toughness of the nanocomposites we...

Aramid paper has been widely used in high-voltage motors and transformers due to its excellent insulation property and thermal durability. However, the smoothness and chemical inertness of aramid fibers lead to a loose structure (voids) of aramid paper, which limits its potential applications in harsh environments, such as high-frequency and high-voltage circuits. This work reports a simple and efficient method to improve the mechanical and insulation properties of meta-aramid paper via controll...

Abstract Aramid fibers exhibit impressive mechanical properties, electrical insulation properties, and chemical stability. However, physical properties of the aramid paper are poor because of the chemical inertness and smooth surface of aramid fibers. This study reports a simple and efficient method for substantially improving the performance of the para-aramid/meta-aramid composite paper by introducing the N,N-dimethylacetamide (DMAc)/LiCl solution to induce partial dissolution or by adding the...

Abstract Separator is a vital component in lithium ion battery (LIB) and its property is directly related to cell performance and safety. However, the current widely used polyolefin separator suffers from lower heat resistant and inferior electrolyte wettability. Therefore, more attention has been attracted in the development of high performance separator. In this study, aramid nanofibers (ANFs), poly(p-phenylene terephthalamide), and heat-resistant polyphenylene sulfide (PPS) nonwoven were used...
