To control contamination resistance of polymer surfaces, the surface hydrophobization and hydrophilization were attempted by atmospheric pressure plasma jet (APPJ)-coating with hexamethyldisiloxane (HMDSO) and APPJ-oxidation, respectively. The APPJ-coating remarkably prevented the deposition of the particulate contaminants in air. The granular morphology was observed on the film surfaces after the APPJ-coating, which resulted in superior contamination resistance via the decrease in the contact area with the contaminant. On the other hand, the APPJ-oxidation promoted the contamination removal in the aqueous detergent system.
