聚合物/贵金属纳米粒子彩虹薄膜的制备及其智能调控变色

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.

高分子薄膜的功能化和智能化是当今薄膜领域的一个研究热点，也是下一代薄膜研发的重大难题。本项目将结合贵金属纳米粒子独特的光学性能和智能高分子的刺激响应性能，制备可智能调控变色的高分子彩虹薄膜。研究包括以下三个方面：1）利用层层自组装制备出七种颜色的高分子/贵金属纳米粒子的单色膜，并应用到生物传感器及表面增强拉曼光谱（SERS）领域。2）制备高分子/纳米金-银核壳棒的复合薄膜，利用偏振光智能调控薄膜的颜色，并开发一系列可智能变色的光学器件。3）提出既能智能变色，又能智能"运动"的双重仿生高分子/纳米金-银核壳棒的复合薄膜，并研究其原理和应用。
