The driving force of this procedure is capillary force(self-assembly) and the water droplet plays the role as template.The morphology and electric property are studied by atomic force microscope and this honeycomb structure is proved to be electro-active. Additionally, the double layer′s formation mechanism is proposed in the systems while the density of organic solvents is higher than that of water.展开更多

The structure of the thin film was characterized by means of X-ray diffraction and UV-Vis absorption spectrum. The results of UV-Vis absorption spectrum indicate that the diameter of the TiO 2 nanoparticles is 2 nm. The results of X-ray diffraction indicate that the thin film is composed of organic and inorganic layers in alternately orderly arrangement. The distance between the organic layer and inorganic layer is 4.61 nm. The thicknesses of organic layer and inorganic layer are 2.58 and 2 nm, respectively.展开更多
