Abstract:

The paper overviews methods of surface chemical modification of inorganic nano-fillers widely used in polymer materials, including small-molecule modifier methods such as coupling agent modification, esterification modification, and macromolecule grafting methods such as surface modification by in-situ graft polymerization. These methods not only solve such problems as easy agglomeration, poor dispersion and poor compatibility of inorganic nano-fillers with polymer materials, but also effectively enhance their performance when applied in the fields of electronics, catalysis, energy, biomedicine and so on. Meanwhile, the modification mechanism, applicable conditions, advantages and disadvantages of various methods are introduced, with prospects on the process optimization and development research direction of the modification methods.
