Spray-On Organic/Inorganic Films: A General Method for the Formation of Functional Nano- to Microscale Coatings

摘要

Surface coatings are important in science and technology with applications that span domains as diverse as biomaterials, optical coatings, photovoltaic cells, or corrosion protection. Such applications were enabled by the development of methods for the preparation of organic and inorganic thin films that either involve transfer through the gas phase (e.g., physical vapor deposition (PVD), chemical vapor deposition (CVD), sputtering) or deposition from solution (e.g., sol-gel methods, spin-coating, electrospraying, spray pyrolysis, electroplating).Many methods are also specific for a given application and only a few are applicable to a wide range of materials and surfaces. A potent and simple solution-based method for the preparation of multicomposite nanoscale films on surfaces of almost any kind and any shape is the well-known layer-by-layer (LbL) method.The introduction of spray-assisted deposition was an important improvement of the LbL technique with respect to accelerating and scaling up of the process.
