Problems solved by technology

However, the current preparation of polymer fiber-based ZnO nanofibers is usually in the form of high-temperature calcination, and the polymer fibers are removed, leaving only short fibers of ZnO nanoparticles or ZnO nanowires. Such a treatment method cannot obtain good mechanical properties and contain a high proportion of Fiber Membrane Material of Nano Zinc Oxide

Abstract

The invention relates to the technical field of fiber manufacturing, and in particular relates to a preparation method of polymer fiber-based ZnO nanowire fiber. The preparation method comprises the following steps: (1) carrying out electrostatic spinning on a polymer solution and a ZnO precursor to obtain nano-fiber containing a polymer and the ZnO precursor; (2) carrying out low-temperature heat treatment on the nano-fiber to obtain the nano-fiber containing uniformly-distributed Zn nanoparticles inside; (3) by combining a hydrothermal method, putting the nano-fiber into a growth solution and growing for a period of time, so that the Zn nano-particles on surfaces of the nano-fiber and inside the nano-fiber are self-assembled and grow into ZnO nanowires, thereby forming the polymer fiber-based ZnO nanowire fiber. The polymer fiber-based ZnO nanowire fiber prepared by the preparation method has a good mechanical property and contains high-ratio nano zinc oxide.
