Low temperature growth of BaFCl microcrystals by a facile one-pot refluxing method and their superhydrophobic property

•A facile one-pot refluxing method was explored for large-scale preparation of BaFCl microcrystals.•BaFCl microcrystals with different morphology have been prepared successfully by adding surfactants.•The products show extraordinary superhydrophobicity with the contact angle above 150°.

In this work, we report a facile solution route to prepare BaFCl microcrystals with different morphologies at low-temperature. The surface morphologies and chemical composition were examined by the scanning electron microscope (SEM) and X-ray powder diffraction (XRD). The wettability of the as-synthesized BaFCl microcrystals (MCs) was studied by the measuring water contact angle (CA). A static CA for water over 150° was observed, which was closely related to both the structure and chemical modification of BaFCl MCs. Furthermore, the as-prepared BaFCl MCs showed superhydrophobicity for some corrosive liquids such as acidic and basic aqueous solutions.
