Outline of Final Research Achievements

In this work, a plate electrode and a mesh electrode were used for lower and upper electrodes, respectively. Particles were piled on the lower electrode and an electric field was produced. Owing to induction charging, the electric charge polarity of the particle layer is identical to that of the lower electrode, leading to particles in the upper layer being levitated by Coulomb forces. The observation of both the particle behavior and the levitation process using a high-speed microscope camera showed that agglomerates as well as individual particles were levitated. The dielectric particles were polarized in the electric field, the electrostatic interaction between which leads to the formation of chain agglomerates. When the magnitude of the total Coulomb force of the primary particles consisting the agglomerate exceeded the interparticle and gravitational forces, the agglomerate levitated.

Academic Significance and Societal Importance of the Research Achievements

微粉体は粒子の集合体であり,粒子間の付着力によって凝集する性質がある。個々の粒子に対して機械的外力を与えて粒子の運動を制御することは難しいが,静電場を用いて一度に多数の粒子に自発的な運動を可能にする駆動力を与えて遠隔で制御することは可能であり,本研究では粒子帯電・浮揚に必須の基礎技術を確立した。本技術は,印加電圧を変数とする簡便な操作で,静電場および粒子の帯電量を制御して,微粒子の分散・凝集制御に応用できるので,これまで難しいと言われてきた微粒子遠隔精密操作を効率的かつ飛躍的に発展させられる。
