Abstract

The invention relates to a conductive nanofiber membrane and a preparation method thereof. The fiber membrane is obtained by performing chemical silver plating by taking a palladium-containing polyacrylonitrile PAN nanofiber membrane as a carrier. According to the preparation method, the conductivity of the nanofiber membrane and the morphology of the nanofiber membrane can be changed by adjustingprocess parameters. The preparation method is novel, simple in process, flexible in adjustment and high in repetition rate; and the membrane is convenient to process, high in flexibility and light and thin and is particularly suitable for application in the field of intelligent textiles.

Description

technical field [0001] The invention belongs to the field of conductive materials and preparation thereof, in particular to a conductive nanofiber film and a preparation method thereof. Background technique [0002] Nanofibrous membrane has the characteristics of controllable fiber scale and structure morphology and porous structure, which can greatly increase the specific surface area, such as catalysts, sensors, filter materials, etc. Among them, conductive nanofiber materials have both the characteristics of nanofibers and excellent electrical conductivity, and can meet some special performance requirements. They have outstanding application performance in the fields of myocardial and nerve tissue engineering, electrical sensors, and electrical energy storage. [0003] Polymer nanofibers prepared by electrospinning are generally non-conductive, which limits their potential applications to a certain extent. After metallizing the nanofibers by physical or chemical methods, ...
