Problems solved by technology

The conductivity of fullerene micro / nanofibers is similar to that of graphite, and its outstanding aspect ratio makes it more conducive to the formation of a chain network structure in the matrix continuous phase than conductive carbon black when added to the matrix, but its main disadvantages are Its dispersion in the polymer matrix is ​​poor, and organic modification of the surface is required to improve the surface polarity, improve the dispersion and interfacial bonding force in the polymer matrix

Abstract

A preparing method of silver nanowire modified fullerene micro / nanofibers is disclosed. The method includes (1) preparing fullerene micro / nanofibers the length-diameter ratio of which is about 1000; (2) preparing sulfydryl functionalized fullerene micro / nanofibers through acidification and further reaction; (3) preparing fullerene fibers anchoring platinum; and (4) preparing the silver nanowire modified fullerene micro / nanofibers on which silver nanowires grow in situ. The silver nanowire modified fullerene micro / nanofibers, and application thereof in preparation of an antistatic PC material are further provided by the invention. The dosage of an antistatic agent of the disclosed fibers is low when reaching antistatic requirements, thus overcoming a problem that different components are separated in phase when fullerene micro / nanofibers are blended with silver nanowires for modification, increasing the probability of formation of a conductive network in a matrix, overcoming a disadvantage that contact resistance in a matrix is high, and improving synergistic effects of two antistatic agents.

Description

Technical field [0001] The invention relates to a fiber material and a preparation method and application thereof, in particular to a silver nanowire modified fullerene micro / nano fiber, a preparation method and application thereof, and belongs to the technical field of antistatic materials. Background technique [0002] Polycarbonate (PC), as one of the five major engineering plastics, is an amorphous, odorless, non-toxic, high-transparency, colorless or yellow thermoplastic. It has excellent impact resistance, tensile strength, full strength, It has high compressive strength, good heat resistance and low temperature resistance, and maintains stable mechanical properties in a wide temperature range. However, the PC body is insulated and the surface does not absorb water, which limits its application in some fields that require antistatic. In recent years, many studies have been devoted to improving the antistatic properties of PC materials by adding antistatic agents. [0003] A...
