We report on the structural analysis of graphene oxide (GO) by transmission electron microscopy (TEM). Electron diffraction shows that average underlying carbon lattice maintains order and lattice-spacings graphene; a structure is clearly resolved in 80 kV aberration-corrected atomic resolution TEM images. These results also reveal single GO sheets are highly transparent stable beam, hence ideal support films for study nanoparticles macromolecules TEM. demonstrate this through physiological...
Graphene is one of the stiffest known materials, with a Young's modulus 1 TPa, making it an ideal candidate for use as reinforcement in high-performance composites. However, being one-atom thick crystalline material, graphene poses several fundamental questions: (1) can decades research on carbon-based composites be applied to such ultimately-thin material? (2) continuum mechanics used traditionally still valid at atomic level? (3) how does matrix interact crystals and what kind theoretical...
The stress transfer between the internal layers of multilayer graphene within polymer-based nanocomposites has been investigated from stress-induced shifts 2D Raman band. This undertaken through study deformation an ideal composite system where flakes were placed upon surface a polymer beam and then coated with epoxy polymer. It is found that rate band shift per unit strain for monolayer flake virtually independent whether it one or two interfaces (i.e., without top coating). In contrast,...
Model composite specimens have been prepared consisting of a graphene monolayer sandwiched between two thin layers polymer on the surface poly(methyl methacrylate) beam. It has found that well-defined Raman spectra can be obtained from single atomic layer and stress-induced band shifts enable strain distribution in to mapped with high degree precision. demonstrated across is relatively uniform at levels applied up 0.6% but it becomes highly nonuniform above this strain. The change...
CoFe2/BaTiO3 hybrid nanofibers (CoFe2/BTO HNFs) have been synthesized via a simple single-spinneret electrospinning followed by calcination and hydrogen-thermal reduction process for microwave absorption. Electromagnetic absorption properties of CoFe2/BTO HNFs with different compositions are compared those pure CoFe2 NFs BTO NFs. The results reveal that the molar ratio 7:3 exhibit superior higher intensity wider bandwidth at smaller absorber thickness. An optimal reflection loss (RL) −82.4...
The deformation of nanocomposites containing graphene flakes with different numbers layers has been investigated the use Raman spectroscopy. It found that there is a shift 2D band to lower wavenumber and rate per unit strain tends decrease as number increases. demonstrated broadening takes place during tensile for mono- bilayer but narrowing occurs when more than two. also characteristic asymmetric shape three or changes symmetrical above about 0.4% it reverts an on unloading. This change in...
There is a pressing demand for efficient electromagnetic interference (EMI) shielding materials with strong wave absorption and low reflection the protection of next-generation communication technologies wearable electronic devices. In this work, silicone rubber/MXene/Fe3O4 (SRMF) composites sandwich-like structure were fabricated using vacuum-assisted dipping curing. The top bottom layers SRMF are magnetic containing Fe3O4 particles rubber (SR), while middle layer 3D conductive network...
Abstract Up to now, low thermally conductive properties and irreversible damage caused by the accidental mechanical failure are still main negative factors for wide application of polymer thermal management materials in microelectronic industry. In this work, we prepared self‐healing polydimethylsiloxane/boron nitride nano sheets (PDMS/BNNSs) composites with high conductivity. PDMS elastomer dynamic reversible imine bond acts as matrix BNNSs NH 2 regularly in‐plane arrangement used filler....
The semimetal characteristic of graphene seriously obstructs its extensive application as a heat-dissipation material in electronic devices. Therefore, it should be urgent to design semiconducting graphene-based structures high thermal conductivity (TC). In this paper, we construct the hybrid composed and other carbon-based monolayers such BC 3 , C N, 6 N. It is shown that may kept while their TCs will increased with increasing zone width. By comparing affiliated side comb-type plane-type...
Abstract In this article, polyamide 6 (PA6), maleic anhydride grafted ethylene‐propylene‐diene monomer (EPDM‐ g ‐MA), high‐density polyethylene (HDPE) were simultaneously added into an internal mixer to melt‐mixing for different periods. The relationship between morphology and rheological behaviors, crystallization, mechanical properties of PA6/EPDM‐ ‐MA/HDPE blends studied. phase observation revealed that (70/15/15 wt %) blend is constituted from PA6 matrix in which dispersed core‐shell...
