Explanation

nanofilm refers to a thin film materials with a thickness of nanometer order of magnitude (1 to 100 nm). These nanofilm can be composed of particles (grains) with the size of nanometer, and can also be composed of single-layer or multi-layer films with the thickness of nanometer, which are called nanoparticle films and nano multilayer films respectively. nanofilm can be classified according to different characteristics and uses, including the following: by layers: single-layer films and multilayer films. By purpose: Nanofunctional thin films and nanostructured thin films. According to efficiency of spare filling: granular film and dense film. By component: organic nanofilm and inorganic nanofilm. There are many methods to prepare nanofilm, including gel sol method, chemical deposition method, self-assembly, Langmuir Blodgett (L-B) film method, physical vapor deposition, vacuum vapor exposition and sputtering. Different preparation methods will lead to nanofilm with different structures, characteristics and functions. These nanofilm are widely used in materials science, nanotechnology and other fields, and can be used to develop advanced materials, sensors, coatings, electronic devices, etc.
