Developing composite materials with the synergistic effects of heterogeneous structures and multiple components is considered as a promising strategy to achieve high-performance electromagnetic wave (EMW) absorbers. To further satisfy demand broadband strong microwave absorption, novel NiS/carbon nanofibers (CNFs)/porous carbon successfully synthesized by hydrothermal chemical vapor deposition using lotus leaves biomass source. A few nanotubes (CNTs) uniformly dispersed Ni nanocrystals have...
This study investigated the effect of different monomer compositions acrylonitrile (AN) and methyl methacrylate (MMA) on synthesis expansion performance thermally expandable microspheres (TEMs). TEMs with ratios, specifically AN to MMA ratios 100:0, 90:10, 80:20, 70:30, were synthesized via free radical suspension polymerization. The inner morphology, crystallinity, blowing agent encapsulation efficiency, ratio analyzed using scanning electron microscopy (SEM), Fourier-transform infrared...
The construction of a nanostructure on the surface carbon fiber (CF) is one most promising technologies to improve properties CF-reinforced composites. Achieving growth nanofilament (CNF) CF at lower temperatures can effectively relieve damage strength, but traditional processes cannot be conducted below 400 °C. In this work, with CuNi nanoalloy as catalyst, continuous CNF–CF product was obtained 300 °C, whose strength and interfacial were simultaneously improved. Mechanical tests show that...
Nitrogen-doped graphene quantum dots (N-GQDs) are widely used in biosensing, catalysis, and energy storage due to their excellent conductivity, high specific surface area, unique size effects, optical properties. In this paper, we successfully synthesized N-GQDs using a facile hydrothermal approach investigated the effects of different temperatures times on morphology structure N-GQDs. The results indicated that gradually increased they eventually aggregated into fragments with increasing...
The continuous preparation of carbon nanotubes (CNTs)/carbon fiber (CF) multiscale reinforcements was realized via one-step chemical vapor deposition (CVD) method. In order to alleviate the damage CF caused by catalyst etching at high temperature, catalytic promoter adopted improve activity catalyst, thus reducing CVD temperature. By adjusting cobalt-based system, effects thiourea concentration on morphology, microstructure and tensile strength CNTs/CF samples were systematically...
Silk nanofibers (SNF) have great applications in high-performance functional nanocomposites due to their excellent mechanical properties, biocompatibility, and degradability. However, the preparation of SNF by traditional methods often requires use some environmentally harmful or toxic reagents, limiting its application green chemistry. In this paper, we successfully prepared using natural silk as raw material solvent stripping technology adjusting concentration solution ratio (the diameter...
Carbon fiber composites as pantograph slide materials are in the development stage, which copper is conductive phase, and addition form size need to be designed. Herein, effects of morphology, mesh on performance, influence contact mode between sliding plate bracket temperature rise were compared analyzed. The resistivity 11.2 μΩ·m with 20 wt% mesh, a relative reduction 91.77%. Importantly, impact strength increased by 14.19%, wear reduced 13.21%; hence, laid layers ideal structure. Further...
Exploring carbon materials is promising for innovative electromagnetic wave (EMW) absorption materials, nevertheless challenged by balancing efficient EMW and continuous large-scale fabrication. In this work, CNTs/CNFs@CF with inimitable 3D network hierarchical structures are fabricated as absorbers via the chemical vapor deposition method. Through detailed characterization of its morphology, structure, composition, magnetic properties, material obtained optimal electromagnetism parameters...
