Abstract

A dispersion technology of an inorganic nano-material comprises the following steps: 1, modifying the inorganic nano-material with isocyanate in the presence of an initiator and a dispersant; and 2, uniformly dispersing the inorganic nano-material by a planet dispenser through adopting a mechanical dispersion method. The nano-material dispersed through the dispersion technology is uniform and does not agglomerate.

Description

technical field [0001] The invention belongs to the technical field of inorganic nanometer materials, and in particular relates to a dispersion technology of inorganic nanometer materials. Background technique [0002] Nanoparticles have many new properties due to their reduced size. For example: surface and interface effects, size effects, quantum size effects, etc. When any material is refined to the nanometer level by high-tech means, the physical and chemical properties of the material will undergo tremendous changes, such as: metals are conductors, but the quantum size effect of nano-metal particles at low temperatures will lead to insulation, Nano-inorganic fungicides have strong bactericidal ability and so on. [0003] Polymer / inorganic particle nanohybrid materials combine the properties of organic polymers and inorganic nanoparticles, which is currently a very active research field. However, the difficulty of maintaining stable dispersion of nanoparticles greatly ...
