Abstract:
We present a small-angle neutron scattering and small angle X-ray scattering study of soot containing carbon nanostructures obtained by laser pyrolysis of hydrocarbons. It is showed that different types of carbon nanostructures release different curves in SANS analysis. Samples revealed fractal model-like structure. It was obtained two different slope coefficients described as surface fractal for C2H2/C2H4 sample (SANS and SAXS measurements) and porosity system for the C2H2/SF6 sample (SANS measurement).
