Double-layer honeycomb structure of 4-dodecylbenzenesulfonic acid(DBSA)-doped polyaniline(PANI) is fabricated in the humidity atmosphere by self-assembly method. 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.
