Tribo electrification between various substrates and platinum was investigated with a number of gases, vapors, and gas mixtures present in order to determine the effects of humidity and gaseous pollution and to investigate the mechanisms of frictional charging. The substrates were formed into discs and rotated against platinum in a chamber which could be evacuated and filled with any gas or gas mixture at pressures up to atmospheric over a range of temperatures. Results confirmed that in pure air, water vapor exerts a predominant influence on electrostatic charging and suggested that a maximum occurs in the generated voltage conditions such that a layer of adsorbed water a very few molecules thick was present. Other experiments indicated that, in the presence of air, most pollutant gases had only a slight effect on the voltage generated. In the presence of air, no gases were found that caused an increase in tribo electrification. (Author)
