- Conventional cleaning methods often fail to completely remove surface films, leaving a thin contamination layer; additionally, solvent cleaning typically leaves a surface residue.
- Plasma cleaner use exposes the surface to a gas plasma discharge, gently and thoroughly scrubbing the surface.
- Plasma cleaning will remove non-visible oil films, microscopic rust or other contaminants that typically form on surfaces as a result of handling, exposure or previous manufacturing or cleaning processes; additionally, plasma cleaning does not leave a surface residue.
- A plasma cleaner can treat both a wide variety of materials – including plastics, metals and ceramics – as well as complex surface geometries
- A plasma cleaner is most commonly used prior to adhesive bonding both to clean away loosely held contaminant residues and to activate the surface for increased bonding strength
Surface Alteration of Polymers
The breaking of polymer surface bonds by plasma ablation leads to the creation of polymeric surface free radicals. The bonding of these surface free radicals with atoms or chemical groups from the plasma leads to the replacement of surface polymer functional groups with new functional groups, based upon the chemistry of the plasma process gas. Typical polymer functional groups formed through plasma surface activation and grafting include: amine amino-carboxyl, carboxyl hydroxyl and fluorination carbonyl.
