Carbon Nanobeads from Brassica Nigra Oil: Synthesis and Characterization
Abstract:Thick films of carbon nanobeads have been prepared by chemical vapor deposition of Brassica nigra oil at 850 °C. Micro-Raman spectroscopy, scanning electron microscopy, transmission electron microscopy and Fourier transform infrared spectroscopy are used to characterize the product. The as synthesized carbon nanobeads displays a spherical morphology with diameters of 0.6–2.5 μm and have the wall thickness of ∼100 nm. An absorption properties study of as-prepared film in Ku-band shows the maximum absorption band width of 0.8 and 0.6 GHz, with absorption efficiency of ∼75–90%.
