Abstract

The invention discloses a polymer microsphere and preparation method and application thereof. Polystyrene is used for making a base sphere with the surface comprising a condensed-nuclei aromatic structure in pi-pi interaction with fullerene, and the structure is obtained by substituting a hydrogen atom on a benzene ring contained in the base sphere by chloromethyl and reacting with condensed-nuclei aromatics. The method includes: using a monodispersed polystyrene microsphere as the base sphere, mixing with catalyst SnCl4, adding aliphatic halogenate varsol, slowly dripping chloromethylation reagent while stirring for substitution reaction, allowing the reacted microsphere to react with the condensed-nuclei aromatics, and washing and drying the obtained microsphere to obtain a polymer microsphere with a fullerene separated liquid chromatographic stationary phase serving as a mobile phase. The preparation method of the surface modified polystyrene polymer microsphere only needs two steps, is simple in process, easy to repeat, suitable for massive production of fullerene and has the advantages of high separation efficiency and effectiveness.

Description

technical field

[0001] The invention relates to the field of polymer compounds, in particular to a surface-modified polystyrene polymer microsphere, a preparation method and an application thereof. technical background

[0002] Fullerene is a kind of hollow cage-like all-carbon molecule composed of 12 five-membered rings and several six-membered rings. In 1985, Kroto, Smalley and Curl studied the formation of carbon dust in interstellar space. , During the mass spectrometry experiment of laser vaporized graphite, it was found that it is the third allotrope of carbon after diamond and graphite. Its special structure endows fullerene materials with excellent properties in superconductivity, magnetism, optics, and catalysis. Among them, C composed of 60 carbon atoms 60 - "Buckminsterfullerene" is exceptionally stable and has perfect spherical symmetry. C 60 The emergence of carbon makes people understand a whole new carbon world, and immediately arouses the widespread atten...
