Silica films with honeycomb-like structure were successfully obtained by emulsion method. Emulsion films prepared by the Dip-Withdrawing method were dried at 180 degrees C for 2 h and sintered at 500 degrees C, the films turned from superhydrophilic to superhydrophobic after being modified by octyltrimethoxysilane (OTMS) to form a self-assembled monolayer (SAM) with low surface energy. The surface structures and the thickness of the silica emulsion films were observed by scanning electron microscopy (SEM), and the results showed that the emulsion method had a similar effect to the phase separation one on producing the honeycomb-like structure that highly influenced the wettability of solid surface.
