石墨烯-聚合物复合微纳结构环境响应机制调控及其在光纤传感中的应用

Optical fiber sensing is an interdisciplinary research field with materials, information, life, chemistry and physics science. The development of sensitive materials plays great important part in it. Graphene-polymer nanohybrids hold huge potential promise in stimuli-response applications, and are good candidates in developing new type of stimuli-response materials. Therefore, there are of great theoretical significance and practical values in studying of graphene-polymer nanohybrids response mechanism and its application in fiber-optic sensing. However, nowdays studies about it are not in-depth enough. Above this, in this project, the response mechanism of graphene-polymer nanohybrids and its regulation of optical fiber sensing performance will be studied. On one side, the response mechanism of nanohybrid systems will be investigated at molecular level. On the other side, the regulation mechanism between nanohybrids structure and optical fiber sensing performance will be clarified through the deep research of material micro-structure influence on its sensing properties. This results will provide theoretical guidance on the precise control of optical fiber sensing application of graphene-polymer nanohybrids at molecular levels, and therefore on the development of new stimuli-response materials and fabrication of high performance devices. This project is feasible in theory. A certain foundation has been laid on the early research stage. It is of high feasibility, great theoretical importance and application values.
