Core–shell composites, Fe3O4@C, with 500 nm Fe3O4 microspheres as cores have been successfully prepared through in situ polymerization of phenolic resin on the surface and subsequent high-temperature carbonization. The thickness carbon shell, from 20 to 70 nm, can be well controlled by modulating weight ratio resorcinol microspheres. Carbothermic reduction has not triggered at present conditions, thus crystalline phase magnetic property micropsheres preserved during carbonization process....
The residual defects and groups in chemically reduced graphene oxide cannot only improve the impedance match characteristic prompt energy transition from contiguous states to Fermi level, but also introduce defect polarization relaxation groups’ electronic dipole relaxation, which are all favor of electromagnetic wave penetration absorption. shows enhanced microwave absorption compared with graphite carbon nanotubes, can be expected display better than high quality graphene, exhibiting a...
A novel MOF derivation method is used to prepare Fe/C nanocubes, which are constructed by a cubic framework of amorphous carbon decorated uniformly Fe@graphitic nanoparticles for microwave absorption.
Highly uniform core-shell composites, polypyrrole@polyaniline (PPy@PANI), have been successfully constructed by directing the polymerization of aniline on surface PPy microspheres. The thickness PANI shells, from 30 to 120 nm, can be well controlled modulating weight ratio and microspheres with abundant carbonyl groups very strong affinity conjugated chains PANI, which is responsible for spontaneous formation microstructures. However, between shells does not promote diffusion or reassembly...
Microstructured Ni/PPy (PPy: polypyrrole) core/shell composites were prepared from an in situ chemical oxidative polymerization of pyrrole (Py) monomer the presence Ni powder, with ammonium persulfate (APS) as oxidant and citric acid (C6H8O7) dopant. X-ray diffraction Fourier transform infrared analyses indicate that there is no interaction between powder protonated PPy. The mass percentages PPy, calculated remanent weight after thermogravimetric analysis, are consistent those designed. soft...
Rational construction of a profitable microstructure in carbon-based electromagnetic composites is becoming promising strategy to reinforce their microwave absorption performance. Herein, the design innovatively coupled with metal–organic frameworks (MOFs)-derived method produce hollow Co/C microspheres (Co/C-HS). The resultant combine advantages microstructures and good chemical homogeneity. It found that pyrolysis temperature plays an important role determining properties these...

One-dimensional microstructure has been regarded as one of the most desirable configurations for magnetic carbon-based microwave absorbing materials (MAMs). Herein, pea-like Fe/Fe3C nanoparticles embedded in nitrogen-doped carbon nanotubes (Fe/Fe3C@NCNTs) are successfully prepared through a direct pyrolysis mixture FeCl3·6H2O and melamine under inert atmosphere. The chemical composition microstructural feature these Fe/Fe3C@NCNTs composites highly dependent on temperature. As result, their...
Well-defined porous Fe3O4 flower-like nanostructures have been synthesized by decomposition of the iron alkoxide precursors that are prepared heating up solution FeCl3·6H2O, urea, and surfactant in ethylene glycol. Time-dependent SEM studies indicate structure evolution contains a fast nucleation primary nanoparticles followed subsequent growth. By varying amount solution, morphology microstructure can be controlled. After calcination, maintained final products Fe3O4, with each petal flower...
Anatase TiO2 nanosheets supported on reduced graphene oxide (RGO) were synthesized via a one-step, solvothermal method. During the step, (GO) was to RGO, and, subsequently, anatase with 73.7% exposed {001} facets grown in situ surfaces of RGO nanosheets. Compared pure TiO2, RGO/TiO2 hybrid nanocomposite had improved photoactivity as result effective photoinduced electron transfer from acceptor through interfacial interactions. Trapping tests showed that oxidation dye molecules proceeded for...
