英文摘要	Tungsten trioxide (WO3) films with novel dandelion-like structures were prepared by spin-coating a sol of WO3 with CTAB (cetyltrimethyl ammonium bromides) on quartz substrates. The resultant WO3 films were characterized by X-ray diffraction (XRD), FT-IR spectroscopy, scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS). The wettabilities of the WO3 films were evaluated by contact angle (CA) measurements. It was found that the WO3 film exhibited superhydrophilicity under UV light irradiation, whereas after storage in the dark for a certain time, it turned to be superhydrophobic.
