Decorating Carbon Nanotubes with Nanoparticles
The unique, well-defined tubular structure of carbon nanotubes (CNTs) continues to attract interest. CNTs are fascinating materials for basic scientific research with the potential for several promising applications in catalysis, electronic devices and chemical biology. In recent years, many efforts have led to the development of versatile methods to modify CNTs to obtain derivatives with more ...
متن کاملMicrowave Synthesis and Magnetic Investigation of CuFe2O4 Nanoparticles and Poly Styrene-Carbon Nanotubes Composites
At the first step CuFe2O4 nanoparticles were synthesized by a fast and facile microwave method. The obtained nanoparticles and modified carbon nano tubes were added to poly styrene matrix. The products were characterized through Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy. Vibrating sample magnetometer shows nanoparticles exhibit ferromagnetic be...
متن کاملMagnetic and microwave absorption properties of barium hexaferrite doped with La3+ and Gd3+
In this paper, BaLaxGdxFe12-2xO19 (x=0.2, 0.4, 0.6 and 0.8) were synthesized via sol-gel auto-combustion method. Fourier transform infrared spectroscopy (FTIR) of samples was represented that the bands at 400 and 500 cm-1 were related to the formation of hexaferrite phase. The (x-ray diffraction) XRD patterns were matched exactly with the structure of barium hexaferrite. (Field emission scanni...
متن کاملInvestigation on magnetic and microwave behavior of magnetite nanoparticles coated carbon fibers composite
Radar absorbing materials, i.e. magnetite (Fe3O4) coated carbon fibers (MCCFs) were fabricated by electro-deposition technique. Black-colored single spinel phase Fe3O4 nanoparticles was easily synthesized by hydrothermal method using reduction of a Fe (III) - Triethanolamine complex in an aqueous alkaline solution at 60-80 ◦C. Uniform and compact Fe3O4 films were fabricated on nitric acid treat...
متن کاملDecorating Silver Nanoparticles onto Multiwall Carbon Nanotube Sheets
Carbon nanotube sheets have great potential for specific engineering applications owing to their unique, tunable properties such as conductivity. To date, most CNT sheet materials (e.g., buckypapers) are fabricated by using single wall carbon nanotubes (SWNTs). However, multi-wall carbon nanotubes (MWNTs) are much cheaper than SWNTs, and better suited to large scale industrial applications. One...
