英文摘要： The multiple-function and intelligentization of polymer films are recent research hot topics and main challenge for next generation polymer films. In this project, we will report the first proof of concept of intelligently controllable chromic rainbow films by combining the unique optical properties of noble metal nanoparticles and stimuli-responsive properties of polymers. Generally, this project can be divided into three sections: 1) polymer/ noble metal nanoparticles hybrid films with seven different colors will be fabricated by layer-by-layer self-assembly method. The applications of obtained films in biosensors and Surface-enhanced Raman spectroscopy (SERS) will also be investigated. 2) The color of polymer/ Au-Ag core-shell nanorods hybrid film can be finely controlled by polarizer, which allows us to design a series of color-tunable optical devices.3) we will report a novel biomimetic polymer/ Au-Ag core-shell nanorods hybrid film, and its self-motion and color can be intelligently controlled. The mechanism and application of this film also be studied.
