Embodiment Construction

[0039] Transmission electron microscopy (TEM) of Au-MCNTs ( figure 1 ) It can be seen that the gold nanoparticles are evenly arranged along the outer wall of the MCNT, and the diameter of the gold nanoparticles is about 12nm, spherical and very uniform. Au-MCNTs will not condense or change color when placed in the dark for several months.

[0040] Made of PA6-Au-MCNT-Ru(bpy) 3 2+ Field emission scanning electron microscopy (FESEM) images of optical composite nanofibers ( figure 2 ) It can be seen that PA6-Au-MCNT-Ru(bpy) 3 2+ Optical composite nanofibers are randomly oriented to form a nanofiber film with a porous 3D structure. The surface of the nanofibers is smooth and unobtrusive, and the diameter ranges from 50nm to 300nm.

[0041] image 3 Cyclic voltammetry (CV) and electrochemiluminescence (ECL) were applied to PA6-Au-MCNT-Ru(bpy) 3 2+ Optical composite nanofibers were characterized. In the CV curve, there is an obvious oxidation peak at +1.07V (vs.Ag / AgCl) ( ...

Abstract

The invention relates to a preparation method of an optical composite nano-fiber material. The method comprises the steps of 1) preparing a nano gold-multi-wall carbon nano tube compound Au-MCNT; 2) preparing a spinning solution; 3) preparing the optical composite nano-fiber material in an electrostatic spinning way. In the electrostatic spinning, the prepared uniform and transparent precursor electrostatic spinning solution is arranged in an injector, a positive electrode of a high-voltage electrostatic generator is connected with a needle, a negative electrode is connected onto a clean bare electrode, the liquid is supplied by adopting a trace injection pump and directly applied to the injector needle through the high-voltage electrostatic power generated by the high-voltage electrostatic generator, and the optical composite nano-fiber is collected onto the bare electrode. The nano gold-multi-wall carbon nano tube compound with good conductivity and large specific surface area and capable of stably and firmly loading a great amount of trisruthenium Ru(bpy)3<2+> is doped with the spinnable macromolecular nylon 6 with good stability to obtain the precursor electrostatic spinning solution, and the optical composite nano fiber is obtained through the one-step electrostatic spinning method.
