Abstract	:	Metal ت metal and to an extent metal ت insulator contact or triboelectric charging are wellknown phenomena with good theoretical understanding of the charge exchange mechanism.However, insulator ت insulator charging is not as well understood. Theoretical and experimentalresearch has been performed that shows that the surface charge on an insulator after triboelectriccharging with another insulator is rapidly dissipated with lowered atmospheric pressure. Thispressure discharge is consistent with surface ions being evaporated off the surface once theirvapor pressure falls below the saturation vapor pressure. A two-phase equilibrium model basedon an ideal gas of singly charged ions in equilibrium with a submonolayer adsorbed film wasdeveloped to describe the pressure dependence of the surface charge on an insulator. Theresulting charge density equation is an electrostatic version of the Langmuir isotherm foradsorbed surface particles, which describestested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
