Controllable BaF2 microcrystals with super-hydrophobic property have been successfully synthesized via a facile hydrothermal process. XRD, SEM and CA were used to study the structure, morphology and the hydrophobic properties of the BaF2 materials. The effects of reaction time, surfactants and pH were investigated in order to get a series of accurate reaction conditions for the preparation of BaF2 material. The results showed that uniform BaF2 cubic phase structure was fabricated when the reaction temperature was controlled at 160 °C for 24 h. In addition, the BaF2 materials showed excellent super-hydrophobic properties. The results of the influence of time and substrates exhibited that the sample could maintain the stable super-hydrophobic property for over 10 days. As a promising superhydrophobic material, the studies of BaF2 reported in this paper have potential application prospect and have a certain guiding meaning for the future study about superhydrophobic materials.
