采用化学气相沉积法制备了仿生层次氮化硼（BN）纳米结构薄膜，并从界面工程（形态改变和化学功能化）两个方面对其润湿性能进行了控制。结果表明，该材料具有从接触角为~5°的超亲水性到接触角为~160°的超疏水性。高度粗糙的垂直-衬底纳米管和纳米片结构具有良好的疏水性，而锥形纳米结构的疏水性较差。另一方面，羟基功能化的氮化硼纳米结构被水滴广泛润湿。
Bio-inspired hierarchical Boron nitride (BN) nanostructure films were grown by a CVD method and two aspects of interface engineering (i.e. morphological changes and chemical functionalization) were applied to control their wetting properties. As a result, a wide range from superhydrophilicity with contact angle (CA) of ~5° to superhydrophobicity with CA of ~160° was obtained. Highly-rough vertical-to-substrate nanotube and nanosheet patterns demonstrated great water-repellency whereas conical nanostructures were less hydrophobic. On the other hand, hydroxyl-functionalized BN nanostructures were extensively wetted by water droplets.
