Corona Discharge Treatment for Surface Modification and Adhesion Improvement

Abstract

Surface modification to improve the adhesion property by means of dry methods such as flame, corona and plasma treatments is commonly used for films, foils and paper-Based substrates. the corona discharge treatment technology is explored here and elaborated on. Subjecting the substrate to a corona discharge may provide greater wettability, higher surface free energy, and higher adhesion performance due to the introduction of polar functional groups at the uppermost surface. in addition, the surface roughness of polymeric materials may also be altered during the bombardment by the species in the discharge. the applied corona dosage, or referred to as watt density in the industry, also plays a great role in the level of surface modification.
