Preventing Color Fading in Artist’s Oil Paintings Based on Nano-PZT Ferroelectric Thin Film

Abstract

Due to the excellent electrical properties, stable temperature characteristics, and abundant material systems of ferroelectric thin film materials, in recent years, ferroelectric devices based on silicon technology have been used in microelectronic mechanical systems, new energy photovoltaics, especially nonvolatile memory and other fields. During the preservation of the artist’s oil painting works, the temperature change will directly cause the physical effects of thermal expansion and contraction of the oil painting and the chemical reaction speed of the material in nature. Therefore, it is of great significance to introduce the technology of nano-PZT ferroelectric thin film into oil paintings to prevent fading. This article aims to study the research on preventing fading of the artist’s oil paintings based on nano-PZT ferroelectric thin films and analyze the characteristics of ferroelectric materials, the application of ferroelectric films, the preparation methods of ferroelectric films, and the basis of the main environmental factors that affect the fading of oil paintings. In the above, we studied the fading process of different concentrations of oil paints under simulated sunlight aging and the effect of different concentrations and thicknesses of PZT ferroelectric thin films coated with nano-TiO2 coatings on the color stability of oil paints. The experimental results show that after five times of simulated solar aging for the four concentrations, the total color difference △E: 0.05% group is the largest, 0.4% group is the smallest, the higher the oil paint concentration, the smaller the color difference, the better the color stability, and the antisimulation of sunlight fading.
