The Generation of Static Charge on High Polymer

The generation of static electricity by the contact and seperation between high polymer substances and metals has been studied. The couples of polystyrene-Pt, Acrylite (polymethylmethacrylate)-Pt, and Teflon (polytetrafluoroethylene)-Pt were examined. It was observed that the surrounning conditions have serious effects on the quantity and sign of generated static charge. The mechanism of generation of electro-static charge has been proposed assuming the energy levels of the localized electrons on the surface of high polymer substances and the change of these energy levels by the absorption of different gases. It was estimated that work functions of polystyrene, Acrylite, and Teflon are 5.74 eV, 5.48 eV and 6.04 eV, respectively.
