Preparation method of vertically-arranged boron nitride nanosheet film and material with surface provided with vertically-arranged boron nitride nanosheet film
The invention discloses a preparation method of a vertically-arranged boron nitride nanosheet film and a material with the surface provided with the vertically-arranged boron nitride nanosheet film. The method comprises the following steps: mixing cheap boron oxide powder as a boron source with metal iron powder and magnesium powder, carrying out ball milling for 0.5 h or more to prepare a reaction precursor, taking metal , ceramic, silk screen, and porous ceramic as deposition substrates, heating to 1200-1300 DEG C in a high-purity ammonia atmosphere by using a tubular atmosphere protection annealing furnace, and carrying out heat preservation for 1-8 h, so that a layer of off-white BN nanosheet film is deposited on the surface of the substrate, the contact angle of the film to water is 144-146 degrees, and the hydrophobic property is good. The invention can be applied to the fields of self-cleaning surfaces, self-lubricating surfaces, metal protection, oil-water separation and the like, especially high-temperature corrosive environments. The preparation process is simple, the reaction conditions are mild, and the used raw materials are boron oxide powder, iron powder, magnesium powder and ammonia gas, are cheap, easy to obtain, non-toxic and harmless, and are suitable for large-scale industrial production.
本发明公开了一种垂直排列氮化硼纳米片薄膜的制备方法及表面设置该薄膜的材料。该方法采用廉价的氧化硼粉末作为硼源，与金属铁粉、镁粉混合后球磨0.5小时以上制备出反应前驱体，然后以金属、陶瓷、丝网、多孔陶瓷等作为沉积基片，利用管式气氛保护退火炉在高纯氨气气氛中加热到1200℃～1300℃并保温1～8小时，在基体表面沉积一层灰白色BN纳米片薄膜，该薄膜对水的接触角为144°～146°，具有良好的疏水性能。可在自清洁表面、自润滑表面、金属防护、油水分离等领域加以应用，尤其是高温腐蚀性环境。本发明制备工艺简单，反应条件温和，所用原料为氧化硼粉末、铁粉、镁粉、氨气，廉价易得，无毒无害，适合大规模工业化生产。
