The morphology and chemical elements were characterized by
using a JEOL JSM-6 field emission scanning electron microscopy
(FESEM) equipped with an energy dispersive X-ray spectroscopy
(EDS) equipment. Further detailed structural information was
obtained by using a Hitachi (Tokyo, Japan) H-8100 transmission
electron microscope (TEM), and the corresponding selected area
electron diffraction (SAED). The X-ray powder diffraction (XRD)
pattern of the products was recorded by using a Advance D8 Xray
diffractometer. The water contact angle (CA) was measured
with 5 lL droplets of deionized water using a contact angle measurement
system (JC2000C1) at room temperature. And Fourier
transform infrared absorbance spectrum (FTIR) was recorded on
a Nicolet FTIR spectrophotometer. In addition, X-ray Photoelectron
Spectroscopy (XPS) measurement was performed to characterize
the chemical bonding states of the products surfaces. The superhydrophobic
surfaces of SiO2-coated SiC nanowires were irradiated
by UV lamps of 100 W (Xu Jiang Nanjing), and the light intensities
of 100 W Hg lamp is about 63,000 lux (9 mW/cm2).
