Abstract

Relationship between tribocharge Q/M of an acrylic powder and contact potential difference of metal beads, with which the polymer was tribocharged, was examined. First a contact potential measuring system for powdered materials was fabricated, which was based on Kelvin method. Tribocharge of the acrylic powder was measured by blow-off method. Metals beads of gold, silver, copper, etc. were employed as the rubbing medium. It was found that the contact potential difference of metal beads was influenced by their surface oxidation. The contact potential difference of metals had a linear relationship with their work function. The Q/M of acrylic powder has a close relationship with contact potential difference of metals qualitatively, but quantitative agreement between Q/M of acrylic powder and contact potential difference was not obtained.
