| Research Abstract |
A novel method was developed to measure the potential difference between a polymer film and metal plate in a separation and re-approach process after contact. The surface potential difference due to the charge generated by the contact increases in the separation process: it was demonstrated that a sudden decrease of the potential takes place at a point in the process. This a direct experimental proof of the fact that the amount of contact charge is determined as residual charge after a charge relaxation process due to gas discharge, not by charge transfer mechanism at the contact.
