英文摘要
The purpose of the present study is to develop a new nanoparticle-classification technique to replace centrifugal separation method. The zeta potential of the particles in the slurry dispersed by bead milling exhibited clear size dependence, which was investigated in detail by AFM. That is, the zeta potential of the smaller silica particles was more negative than that of larger silica particles. Hence, the particles were classified using an EFFF system. Using a low applied potential of 5 V, the silica particles with the size from 50 to 200 nm were able to be classified. This method prevented deposition of negatively charged silica particles in the apparatus and allowed continuous operation.
