Abstract

The invention discloses a manufacture method for polystyrene / cassiterite nucleocapsid microsphere that adopts self-assembly method in solution to make nucleocapsid microshere, uses micro-emulsion polymerization to make polystyrene microsphere and sol gel method to make nm cassiterite, uses self-assembly method in solution to made polystyrene / cassiterite nucleocapsid microsphere. It disperses polystyrene microsphere in the NaCl water solution, cationic surface active agent, anionic surface active agent, and cationic surface active agent water solution. The polystyrene microsphere is dispersed in NaCl water solution adding nm cassiterite, taking centrifugal separation, washing, drying to gain polystyrene / cassiterite nucleocapsid microsphere. The process is easy to control. The invention has the advantages of low consumption, common material, equal cassiterite layer.

Description

Technical field:

[0001] The invention relates to a preparation method of polystyrene / tin dioxide core-shell microspheres, in particular to the preparation of polystyrene / tin dioxide core-shell microspheres by a self-assembly method in a solution, and belongs to the field of chemistry and material preparation. Background technique:

[0002] The research and development of new composite materials and new composite methods have always been favored by people. Polymer materials and nano-semiconductor materials have different physical and chemical properties. It is a new type of core-shell microspheres to make them into core and shell respectively. way of compounding materials. Nano-tin dioxide is a widely used semiconductor functional material, which can be used in functional devices such as gas sensors, glass electrodes, electronic transistors, and solar cells. Combining it with polymer materials to prepare materials with special structures and properties will be an important w...
