Electrspun Composite Micro/Nano Fibers For Humidity Detection And Photocatalytic Degradation Of Pollution Water

Clean and healthy environment is very important for people's health. However, numbers of adverse factors have affected the human environment quietly. It is highly desired to find appropriate route to monitor and protect the envirinment. In recent years, nanomaterials have attracted considerable attention in atmospheric monitoring and protection, monitoring and protection of water resources, and some other aspects, due to their surface properties and nano-effect. Electrospinning nanofibers are a kind of unique one-demensional nanomaterials, which exhibit a series of advantages for enviomental applications. The main benefits include large surface area, uniform and controllable diameter, changeful components, high aspect ratio, three-dimensional open structure, additionally, the electrospun nanofiber membranes are a unity of the macro and micro. In present work, we fabricated various types of electrospun composite micro/nano fibers and envaluated the application for environment detection and protection. There are three parts:(1) Preparation and characterization of Li+ doped-ZnO inorganic/inorganic composite nanofibers, and evaluation of the propeties of the humidity sensors based on them. (2) Preparation and characterization of Ag/AgCl coated PAN core-shell nanofiber membranes, and study of the visible-light photocatalytic degradation towards dye in water. (3) Preparation and characterization of Ag/AgCl composite nanoparticle/PAN nanofibers, and study of the visible-light photocatalytic degradation towards dye in water. In summary, the present work will provide a series of new methods to prepare functional nanomaterials, as well as many valuable data for environmental detection and protection by electrospinning.
