We report a novel, facile and general approach, in situ nanopressing, to integrate nanoparticles and polymers in a thin film configuration, where both nanoparticles exposure and film robustness are indispensable for applications. By simply pressing silica nanoparticles into a polymer thin film under an external force, we successfully attained a nanoparticles-polymer thin film, where the silica nanoparticles were partly embedded in the polymer thin film. The outstanding characteristic of easy-to-fabricate nanoparticles-polymer thin films combined the properties of both materials, giving excellent antireflective and antifogging properties, as well as enhanced the robustness of composite thin film. This in situ nanopressing may not only provide an alternative to meet the challenge of constructing mechanically robust nanoparticles-polymer thin films that require nanoparticles on the film surface, but also enrich the methodology to integrate nanoparticles and polymers.
我们报告了一种新颖、简便且通用的方法,即原位压印,可将纳米粒子和聚合物集成在薄膜结构中,其中纳米粒子的暴露和薄膜的坚固性对于应用都是必不可少的。通过在外力下将二氧化硅纳米粒子简单地压入聚合物薄膜中,我们成功地获得了纳米粒子-聚合物薄膜,其中二氧化硅纳米粒子部分嵌入聚合物薄膜中。易于制造的纳米粒子-聚合物薄膜的突出特点结合了两种材料的特性,具有优异的抗反射和防雾性能,并且增强了复合薄膜的坚固性。这种原位压印不仅可以提供一种替代方法来满足构建需要在薄膜表面上具有纳米粒子的机械坚固的纳米粒子-聚合物薄膜的挑战,而且还可以丰富集成纳米粒子和聚合物的方法。
