Abstract

The particle dispersing method includes the following steps: mixing the particle to be dispersed with surfactant via stirring to form suspension; ultrasonically vibrating the mixed suspension for set time; mixing the vibrated solution with base material; and heating the base material to evaporate the surfactant. The corresponding particle dispersing apparatus is also provided. The present invention has excellent dispersion effect, and the method may be used in adding nanometer particle into heat interface material.

Description

【Technical field】 [0001] The invention relates to a particle dispersion method, in particular to a particle dispersion method and equipment using ultrasonic vibration. 【Background technique】 [0002] Due to the effect of van der Waals force, the smaller the particles, the more obvious the agglomeration phenomenon, such as the agglomeration of nanoparticles is extremely easy, which will lead to the decline of its nanometer performance and affect the application and development of nanotechnology. [0003] Therefore, the nanoparticles must be fully dispersed, and the greater the degree of dispersion, the better the effect and the more fully the nano-related properties can be used. Usually adding nanoparticles (such as nano-metals or carbon nanotubes) to the thermal interface material can improve the thermal conductivity of the thermal interface material and increase the thermal conductivity. Among them, nanoparticles need to be uniformly dispersed in the thermal interface mate...
