Optimization via response surface methodology for Ni-La-V2O5 porous ion-storage film by sol–gel method
V2O5 films with high ion storage capacity (Q) and wide optical modulation range (∆T) have great potential for application in electrochromic devices. In this paper, Ni-La-V2O5 porous ion storage films are prepared by the sol–gel method. The effects of Ni-La co-doping content, PEG content, and heat treatment temperature on the properties of V2O5 films were investigated. By comparison, it was found that the Q value of 9 mol% Ni-5.5 mol% La-V2O5 film was increased compared to 9 mol% Ni-V2O5 film, but ∆T was decreased. In order to improve ∆T, Ni-La-V2O5 porous ion storage films were prepared using Ni-La co-doping and PEG pore-former, and the optimization of process parameters was carried out via Response Surface Methodology (RSM). The RSM results showed that the influence on the Q value was in the following order: heat treatment temperature > Ni-La co-doping content > PEG content. Under the near-optimal process parameters, a satisfying V2O5 film with a high Q value (120.23 mC/cm2), a good ∆T (79.8%), and a short response time (3.1 s/2.8 s) were obtained, which further demonstrated the superior electrochromic performance.
期刊介绍：
The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
