Abstract

The invention relates to a preparation method of doping type fluorescent micron-nano fibers, relating to a preparation method of fluorescent fibers and solving the problems of complex method realizing fluorescent light with different colors through the traditional organic fluorescent fibers of a monogenic dye, poor spectrum stability and short service life of physically blended organic fluorescent fibers and large diameters of the traditional organic fluorescent fibers. The preparation method of the doping type fluorescent micron-nano fibers comprises the following steps of: dissolving dialdehyde triphenylamine and poly [2-methoxyl-5(2'-ethylhexoxy) para-phenylacetylene] into a polymer solution according to different mass ratios; and then carrying out electrostatic spinning to obtain the doping type fluorescent micron-nano fibers. The doping type fluorescent micron-nano fibers have good fluorescence spectrum stability, long service life reaching two years and diameters of 10 nanometers-3 micrometers, and can be used in the life and highly technical fields of textile clothing, aviation, navigation, national defense industry, building decoration, transportation, night operation, daily life, amusement, leisure, optical-fiber communication, laser waveguide, and the like.

Description

technical field [0001] The invention relates to a preparation method of fluorescent fibers. Background technique [0002] Fluorescent materials refer to substances that can fluoresce under various types of energy excitations. Fluorescent materials are widely used in waveguide laser emission and communication, bill anti-counterfeiting, screen display, clothing and textiles, information recording, optical computers, explosive sensors, biomolecular probes and many other high-tech fields. The fluorescence characteristics of fluorescent fibers are a very important index. Fluorescence characteristics include excitation wavelength, emission wavelength, characteristic peak, fluorescence intensity, fluorescence fastness and fluorescence stability of fluorescent materials. To meet the application purpose, the main focus is on fluorescence intensity , fluorescence fastness and fluorescence stability three indicators. Organic fluorescent fiber is a combination of organic fluorescent m...
