Method for preparing organic-inorganic composite materials

摘要

A method for preparing organic-inorganic composite materials is provided. It is a dispersion method that the inorganic phase is introduced into the polymer matrix uniformly. The core-shell structure, in which the inorganic materials are core and the organic materials are shell, is formed by first wrapping the inorganic materials with the organic materials in the same reactor. Therefore, the match between the polarity of inorganic phase and the polarity of polymer phase is increased.

1. A method for preparing organic-inorganic composite materials comprising:
1) using a first solvent to prewet an introduced inorganic material, and uniformly stirring the introduced inorganic material; 2) adding a surface active agent or silane with a functional group to perform surface modification to the introduced inorganic material, and uniformly stirring the introduced inorganic material; 3) adding a first polymer to wrap the modified introduced inorganic material to form a core-shell structure in which a center part is an inorganic core, and an outer part is an organic shell, uniformly stirring the modified introduced inorganic material; and then 4) adding a second solvent and a second polymer, and uniformly stirring to form a uniform solution.
