Abstract Porous three-dimensional SiC/melamine-derived carbon foam (3D-SiC/MDCF) composite with an original open pore structure was fabricated by the heat treatment of commercial melamine (MF), carbonization stable MF, and chemical vapor deposition ultra-thin SiC coating. Scanning electron microscopy (SEM) X-ray diffraction (XRD) were employed to detect microstructure morphology as-prepared composites. The results indicated that 3D-SiC/MDCF composites coating prepared successfully. obtained...
Herein, a supermolecular-scale cage-confinement pyrolysis strategy is proposed to build two dielectric electromagnetic wave absorbents, in which MoO2 nanoparticles are sandwiched uniformly between porous carbon shells and reduced graphene oxide (RGO). Both sandwich structures derived from hybrid hydrogels doped by different crosslinkers (with/without oxygen bridge), can precisely confine Mo source (e.g., PMo12 ). Without adding magnetic components, both absorbents exhibit excellent low...
Novel three-dimensional SiC/melamine-derived carbon foam composite filled by silica aerogel (SiC/MDCF–Aerogel) was first fabricated the pyrolysis process of commercial melamine foam, chemical vapor deposition ultrathin SiC films, and sol–gel method aerogel. The results indicated that SiC/MDCF–Aerogel consisted open-celled network structure pregnant in pores. Tiny cracks on interface skeletons clumps were induced during aging process, which drastically beneficial to microwave-absorbing...
The porous structure has been proved to be beneficial improve the microwave absorption performance. In this article, SiC coating reinforced carbon foam (SiC/C) was synthesized via direct pyrolysis of melamine and chemical vapor deposition process coating. Then wrapping architecture consisting three-dimensional ultrathin annealed at elevated temperature. result shows that anneal temperature does have a big impact on dielectric property as real imaginary permittivities remain certain level...
Three underlying root causes for ultrahigh initial coulombic efficiency (99.4%) of Na-storage cobalt sulfide nanoarrays.
In the present study, unique three-dimensional graphene coated nickel (Ni/C) foam reinforced silicon carbide (Ni/[email protected]) composites were first obtained via precursor impregnation and pyrolysis (PIP) processes. The microstructure images indicated that SiC fillers successfully prepared in skeleton pores of Ni/C foam. influence PIP cycles on microwave absorption performances was researched, results after primary process, Ni/[email protected]–I possessed optimal absorbing performance...
Abstract Deep subwavelength highly confined and long-range optical propagation is vital for photonics integration. However, the performance of guided mode could be improved by trade-off between light confinement loss. Here, we demonstrate a high-performance hybrid waveguide consisting high-index nanowire separated from linear array low-index dielectric gap. The significantly achieves plasmonic platform optimization based on combination few-layer graphene (FLG) hexagonal boron nitride (hBN)...
A novel hybrid foam composite consisting of the three-dimensional (3D) interconnected carbon (CF) and ultrathin silicon carbide (SiC) coating was prepared via carbonization, chemical vapor infiltration, deposition process. By means incorporating pyro SiC on surface CF skeleton, not only thermostability compression resistance but also electromagnetic absorption performances as-prepared composites were enhanced. The results that thermostable, as beyond 87% weight remained in air atmosphere at...
A double network nested SiC<sub>nw</sub>/CF foam composite was fabricated with outstanding absorbing properties.
In article number 2001686, Zhaofeng Chen, Meiling Wang, Jiadong Zhou, Yizhong Huang, and co-workers realize uniform MoO2 clusters sandwiched between porous carbon shells RGO support by a supermolecular cage-confinement pyrolysis route. The introduction of crosslinkers into hydrogel precursors have remarkable adjustment effects on low-frequency electromagnetic wave absorption traits.
A low-cost and easily prepared Ni-based composite with outstanding efficient microwave absorption properties was synthesized via the precursor impregnation pyrolysis (PIP) process, in which Ni foam first soaked into a polycarbosilane/xylene solution, followed by under an Ar atmosphere after being dried air. The PIP cycles showed marked impact on reflection loss effective bandwidth that it possessed minimum value of −54.96 dB at 3.35 mm frequency 8.08 GHz. Besides, superior from 7.20 to 11.14...
