Method for preparing fullerenes nano micron fibre

Abstract

The process of preparing nanometer and micron fullerene fiber includes: grinding fullerene material to reach metal luster, dissolving in organic solvent to obtain saturated solution, irradiating with visible light to form colloid solution, mixing with certain amount of lean solvent, setting in thermostat for certain time to separate out monocrystalline nanometer and micron fullerene fiber in millimeter to centimeter level length. The process is simple, feasible and repeatable, and the monocrystalline fullerene fiber with high length-to-diameter ratio and high purity may be applied in fuel cell electrode, catalyst, low dimensional semiconductor, etc.

Description

technical field

[0001] The invention relates to the field of fullerene-based nano-micron materials, in particular to a preparation method for fullerene-based nano-micron fibers. Background technique

[0002] Low-dimensional nano-micron carbon materials are ideal systems for studying the size and dimensional effects of physical properties such as electron transport behavior, optical properties, and mechanical properties. Therefore, low-dimensional nano-micron carbon structure materials are the frontier and hot spot in the field of nano-micron material science.

[0003] Since the discovery of fullerene C by Kroto et al. in 1985 60 Fullerenes have unique physical and chemical properties due to their highly symmetric, spherically delocalized π-electron conjugated systems. The strange photophysics, electrical conductivity, photoconductivity and light-limited behavior of fullerene have aroused great interest of scientists. After more than 20 years of research, organic fullerene ...
