Abstract

The invention discloses a plasma preparation method of polystyrene fluorescent microspheres and reaction equipment of the plasma preparation method, and relates to the technical field of organic synthesis of fluorescent microspheres. A rare earth organic complex is adopted as a starting raw material, plasma of polystyrene is polymerized on the surface of the rare earth organic complex to coat the surface of the rare earth organic complex with a layer of polystyrene, and thus polystyrene fluorescent microspheres are formed. The method includes the main steps of 1, performing plasma pretreatment of the rare earth organic complex; 2, performing plasma polymerization, wherein plasma of polystyrene monomers is polymerized and deposited on the surface of the rare earth organic complex. The polystyrene fluorescent microspheres obtained through the preparation method have a long fluorescent lifetime and good heat stability, and the preparation process is simple, easy to perform and free of environmental pollution.

Description

technical field [0001] The invention relates to the technical field of organic synthesis of fluorescent microspheres. Background technique [0002] Polymer fluorescent microspheres refer to polymer microspheres with a diameter between nanometers and micrometers and loaded with fluorescent substances, and their shape is generally spherical. Among them, fluorescent microspheres have great application potential in the fields of labeling, information analysis, detection, immobilized enzymes, immunomedicine, and high-throughput drug screening due to their stable morphological structure and stable and efficient luminous efficiency. Therefore, in recent years, the research on high-performance polymer fluorescent microspheres has attracted more and more attention from researchers at home and abroad, and has become a hot and difficult research topic in this field. Polymer fluorescent microspheres containing rare earth organic complexes not only have the high-efficiency luminescence ...
