Abstract

The charge on two sets of 100 μm polystyrene particles has been measured using their acceleration in an externally applied electric field. This allows for the measurement of the individual charge on multiple particles at the same time. It is found that particles will charge each other both positively and negatively due to the triboelectric effect. This leads to a broad particle-charge distribution with positive, negative and neutral particles. The particle charge can be largely removed by applying a plasma over the particle containing surface. After plasma charge removal, the particles are triboelectrically recharged when they come into contact with other materials.
