Abstract:

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.
