Glucosan controlled biomineralization of SrCO3 complex nanostructures with superhydrophobicity and adsorption properties

Here we report the in vitro biomineralization of SrCO3 complex nanostructures obtained usin(g) glucosan as the modifier in dimethyl formamide (DMF)-deionized water (DIW) mixed solvents. Rod-, dendrite-, dumbbell-, and sphere-like SrCO3 nanostructures were achieved by tuning the volume ratios of DMF/ DIW, reaction time, and concentrations. The phase, structure, and morphology of the as-obtained products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR) spectroscopy, and Brunauer-Emmett-Teller (BET) analysis. The possible formation mechanism of SrCO3 complex nanostructures follows the rod-dumbbell-sphere growth process. The as-synthesized SrCO3 complex nanostructures show excellent adsorption properties and superhydrophobicity, which may open up a wide range of potential applications in environmental protection.
