Abstract
In this work, we prepared PEI/TiO2/SiO2 multilayer films from the Polyethyleneimine (PEI) solution, TiO2 and SiO2 colloidal solutions. To investigate the influence of the substrate pretreatment, the multilayer films were fabricated on the quartz slides with or without oxygen plasma treatment. The SEM and AFM analyses indicated that PEI/TiO2/SiO2 multilayer films demonstrated low roughness and a uniform purple structural color on the oxygen plasma pretreated quartz substrates. The results showed that this technique could be used in fabricating multilayer films from dilute solutions.
