10/12/2015· Nano silicon carbide (SiC) designed chitosan nanocomposites were prepared by solution technique. Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) were used for studying structural interaction of nano silicon carbide (SiC) with chitosan.
Fourier-transform infrared (FTIR) and X-ray diffraction (XRD) results show that the black structures were composed of β-silicon carbide (β-SiC), which can be attributed to the pyrolysis of the PDMS.
In this study, the influence of filler shape and filler content on the physical and mechanical properties of silicon carbide/epoxy nanocomposites was investigated using silicon carbide nanoparticles and nanowhiskers. Samples containing 0.5, 1, 2 and 4 wt% of β

Silicon carbide fits into both egories, being a wide band-gap semiconductor and a ceramic with hardness nearly equal to that of diamond. The research presented here describes discov-eries that are important contributions to understanding not only the
The synthesis of silicon carbide (SiC) fibers by electrospinning method was done using polycarbosylane (PCS) as precursor and dimethylformamide (DMF)/toluene as solvent. Knowing the heat treatment of fibers consist of curing and pyrolisis, there were two steps in the major reaction.
