Abstract
This paper describes a study of relative humidity effects on the adhesion of small particles to surfaces. Ambient dust ranging in size from less than one micron up to 140 microns was used as test particles. A 20 psi nitrogen blowoff was used as the removal mechanism to test for particle adhesion. Particles were counted before and after blowoff to determine retention characteristics. Particle adhesion increased drastically as relative humidity increased above 50%. The greatest adhesion changes occurred within the first hour of conditioning time. Data are presented for total particle adhesion, for particles 10 micron and larger, and 50 microns and larger.
