The coating of thin films is applied in numerous fields and many methods are employed for the deposition of these films. Some coating techniques may deposit films at high speed; for example, ordinary printing paper is coated with micrometre-thick layers of clay at a speed of tens of meters per second. However, to coat nanometre thin films at high speed, vacuum techniques are typically required, which increases the complexity of the process. Here, we report a simple wet chemical method for the high-speed coating of films with thicknesses at the nanometre level. This soap-film coating technique is based on forcing a substrate through a soap film that contains nanomaterials. Molecules and nanomaterials can be deposited at a thickness ranging from less than a monolayer to several layers at speeds up to meters per second. We believe that the soap-film coating method is potentially important for industrial-scale nanotechnology.
薄膜的涂层在许多领域都有应用，并且有许多方法可用于这些薄膜的沉积。一些涂层技术可以高速沉积薄膜；例如，普通的打印纸以每秒数十米的速度涂覆有几微米厚的粘土层。但是，要高速涂覆纳米薄膜，通常需要真空技术，这会增加工艺的复杂性。在这里，我们报告了一种简单的湿法化学方法，可用于高速涂覆厚度为纳米级的薄膜。这种肥皂膜涂层技术基于迫使基底通过包含纳米材料的肥皂膜。分子和纳米材料可以以每秒米的速度沉积单层以下至数层的厚度。我们相信，肥皂膜涂层方法对于工业规模的纳米技术可能非常重要。
