    Notes: The carbon nanotubes were prepared by catalytic decompose of benzene using floatingtransition method at 1100~1200℃. Benzene was used as carbon source and iron as catalyst withsulfur. The carbon nanotubes are straight with diameter 30~80nm, internal diameter 10~50nm andlength 50~100μm. The carbon nanotubes and epoxy resin were sufficiently mixed. The mixturewas smeared on to a pure aluminum plate layer by layer until the thickness of the composite layerreached 1.0 mm. The coating resin was cured by heating under infrared radiation. Complexpermittivity, permeability and microwave reflectivity of carbon nanotubes reinforced epoxy resincoating had been investigated at the frequency ranges of 8.2~12.4GHz and 2~18GHz respectively.The real part (ε′) of complex permittivity of this coating ranges from 14.87 to 13.86, and theimaginary part (ε″), from 6.42 to 5.87, the loss tangent tgδε (ε″/ε′), from 0.42 to 0.45. The real part(μ′) of complex permeability of this coating ranges from 1.02 to 1.14, and the imaginary part (μ″),from 0.08 to 0.11, the loss tangent tgδμ (μ″/μ′), from 0.06 to 0.11. The maximum absorbing peak ofthe carbon nanotube reinforced epoxy resin coating is 22.89 dB at 11.40GHz. The band width(R〈-10dB) of this coating with thickness of 1.0 mm is 3.0GHz, band width (R〈-5dB) is 4.7GHz atthe frequency range of 8~18GHz. This carbon nanotube reinforced epoxy resin coating would be agood candidate for microwave absorbing material

    Notes: The carbon nanotube/PMMA/PVAc composite film was prepared by solution casting.The carbon nanotube (CNT) and graphitized carbon nanotube (GCNT) were employed asconductive fillers in the composite films. The conductivity of the GCNT/PMMA/PVAc film isbetter than that of CNT/PMMA/PVAc film. The electrical percolation thresholds were at 5wt% and2wt% respectively in the CNT/PMMA/PVAc film and GCNT/PMMA/PVAc film. The volumeelectric resistivities of CNT/PMMA/PVAc and GCNT/PMMA/PVAc composite film are at0.044[removed info]⋅m and 0.007[removed info]⋅m respectively at 15wt% carbon nanotube. The significant difference ofresistivity for the both types of composite film was due to different structure and crystallinity ofCNT and GCNT

    Notes: The microwave permittivity of multi-walled carbon nanotubes blended in paraffin waxhas been studied in the frequency range from 2 to 18GHz. The dissipaton factors of themulti-walled carbon nanotubes are high at the microwave frequencies. The microwave permittivityof the multi-walled carbon nanotubes and paraffin wax (or other dielectric materials) compositescan be tailored by the content of the carbon nanotubes. And ε′, ε″and tgδ of the composites increasewith the volume filling factor (v) of the carbon nanotubes. The ε′ and ε″ of the multi-walled carbonnanotubes decrease with frequency in the frequency range from 2 to18 GHz. This property is verygood for broadband radar absorbing materials. The classical effective medium functions can noteffectively model the microwave permittivities of the composites containing multi-walled carbonnanotubes. The ε′ and ε″ can be effectively modeled using second-order polynomials (ε′,ε″=Av2+Bv+C). The high ε″ and dissipation factor tgδ (ε″/ε′) of multi-walled carbon nanotubes aredue to the dielectric relaxation. The carbon nanotubes composites would be a good candidate formicrowave absorbing material electromagnetic interface (EMI) shielding material

    Notes: The nano SiC(N) composite powder was synthesized from hexamethyldisilazane((Me3Si)2NH) (Me:CH3) by a laser−induced gas-phase reaction. The microwave permittivity of thenano SiC(N) composite powder and paraffin wax (or other dielectric materials) composites can betailored by the content of this nano powder. The dissipation factors (tgδ) of the nano SiC(N)composite powder are high at the microwave frequencies. And ε′, ε″ and tgδ of composites increasewith the volume filling factor (v) of nano SiC(N) powder. The nano SiC(N) composite powderwould be a good candidate for microwave absorbing material and electromagnetic interface (EMI)shielding material. The classical effective medium functions can not effectively model themicrowave permittivities of the SiC(N) nanocomposites. We found that the microwavepermittivities of the nanocomposites can be effectively modeled using second-order polynomials.These polynomials are dependent only on the filling factor and are purely mathematical models.The ε′ and ε″ of nanocomposites can be effectively modeled using second-order polynomials (ε′,ε″=Av2+Bv+C)

    Notes: The magnetite (Fe3O4) nanoparticles were prepared by coprecipitation of Fe3+ and Fe2+ withaqueous NaOH solution. The Fe3O4/polyaniline (PANI) magnetic composite nanoparticles withcore-shell structure with diameter of 30-50 nm were prepared via an in-situ polymerization ofaniline in aqueous solution containing Fe3O4 magnetic fluid. The inductive heat property ofFe3O4/polyaniline composite nanoparticles in an alternating current (AC) magnetic field wasinvestigated. The potential of Fe3O4/polyaniline nanoparticles was evaluated for localizedhyperthermia treatment of cancers. The saturation magnetization Ms and coercivity Hc of Fe3O4nanoparticles are 50.05 emu/g and 137 Oe respectively, the Fe3O4/polyaniline compositenanoparticles, 26.34 emu/g and 0 Oe. Exposed in the alternating current (AC) magnetic field for 29min, the temperatures of physiological saline suspension containing Fe3O4 nanoparticles orFe3O4/polyaniline composite nanoparticles are 63.6 ℃ and 52.4 ℃ respectively. TheFe3O4/polyaniline composite nanoparticles would be useful as good thermoseeds for localizedhyperthermia treatment of cancers

    Notes: The filling of multi-walled carbon nanotubes with metallic silver nanowires via wetchemistry method was investigated. The carbon nanotubes were filled with long continuous silvernanowires. The carbon nanotubes were almost opened and cut after being treated with concentratednitric acid. Silver nitrate solution filled carbon nanotubes by capillarity. Carbon nanotubes werefilled with silver nanowires after calcinations by hydrogen. The diameters of silver nanowires werein the range of 20-40 nm, and lengths of 100 nm - 10 μm. We studied the micromorphology of thesilver nanowires filled in carbon nanotubes by transmission electron microscopy (TEM) and X-raydiffraction (XRD). Based on the experimental results, a formation mechanism of the Agnanowire-filled carbon nanotubes was proposed

    Notes: The carbon nanotubes (CNTs) were prepared by catalytic decompose of benzene usingfloating transition method at 1100-1200°C. Benzene was used as carbon source and ferrocene ascatalyst with thiophene. The carbon nanotubes are straight with diameter 20-50 nm, internaldiameter 10-30 nm and length 50-1000 μm. The carbon nanotube and continuous carbon fiber(T300) reinforced unidirectional epoxy resin matrix composites was fabricated. The volune fractionof continuous carbon fiber (first filler) in the composites without second filler (carbon nanotube)was 60%. The mechanical properties of the composites were investigated under bending, shear, andimpact loading. The flexural strength and modulus of the composites increased firstly and thendecreased with the increasing of carbon nanotube contents in epoxy resin matrix. The flexuralstrength of the composites reached the maximum value of 1780 MPa when the weight percent ofcarbon nanotube in epoxy resin matrix was 3%
