A mass of nanoparticles/nanorods were formed on a simultaneously deposited gran- ular film by plasma enhanced chemical vapor deposition(PECVD)of perfluorohexane at atmo- spheric pressure without any catalysts or templates.Scanning electron microscopy(SEM)and X-ray photoelectron spectroscopy(XPS)were used to characterize the morphology and the chem- ical compositions of nanoparticles.The average size of particles is about 100 nm and the length of synthesized nanorods is between 1 μm and 2.5 μm.The analyses of transmission electron mi- croscopy(TEM),high-resolution transmission electron microscopy(HRTEM),selected area elec- tron diffraction(SAED)and X-ray diffraction(XRD)reveals that the nanoparticles and nanorods are crystalline.
Polymeric polypyrrole-like (PPy-like) nanocrystallines were fast synthesized through oriented plasma polymerization at atmospheric pressure and room temperature. The effects of discharge power on the nanocrystalline morphology were investigated. Larger power tends to produce longer nanocrystallines. 3 mm long nanowires were produced at the largest power in our experiment. TEM image and the sharp electronic diffraction spots in SAD suggest that the nanoparticles have a single crystal phase. The chemical structure of the nanocrystalline has been studied through FTIR, EDX etc. This novel polymerization method could have great applications in fabricating functional polymeric nanocrystallines.
