| 英文简介 | Because of global warming and inland location, the climates of some region of Inner Mongolia are extremely dry and the desert area tends to expand, which not only affect the health of local residents and ecological environment but also have a potential influence on the environment of surrounding city. Therefore, how to improve the dry environment and create a good ecological environment has become a hot research topic and exploring an effective new method and producing a new material to control the humidity is more and more important. Recently, photo-responsive materials which can provide remote, precise and contactless control have aroused significant research interest. In this project, a smart nanomaterial with sheath-core structure and photoresponsive tunable wettability is obtained by using spiropyran units modified on the surface of one-dimensional electrospun nanofibers; the effective preparation method of one-dimensional nanofibers modified by spiropyran units is established and the best preparation technics will be found out; the structure and performance change of these spiropyran complex and modified nanofiber-material under ultraviolet-visible light irradiation are investigated systemically and the photochromic reaction mechanism is also ascertained. And during the process of wettability change, the synergistic effect between photoisomerization of spiropyran chromophore and the dehydration of polar group on the surface of nanofibers will be explored; we analyze the control of the smart nanomaterial on humidity within a small space, which can provide a theoretical basis for the further application. This smart nanomaterial fully utilizes the solar energy and accordingly reduces the energy consumption, which has a very attractive prospect. |
