Application of a thin polymeric coating to the polymer film provides the improved performance of the printed conductors.
METHOD FOR PRODUCING CONTACT LENSES WITH WEARING COMFORT
The invention is related to a method for producing silicone hydrogel contact lenses with a stable lubricious hydrogel coating thereon providing a low surface friction. A method of the invention comprises forming a plasma-reactive hydrophilic polymer hybrid base coating having reactive functional groups on a silicone hydrogel contact lens and heating the silicone hydrogel contact lens with the hybrid base coating in an aqueous solution of a water-soluble and thermally crosslinkable hydrophilic polymeric material to form a stable lubricious hydrogel coating thereon.
Plasma treatment of an elastomeric material for adhesion
Elastomeric components, such as a shoe outsole, are treated with a plasma application to clean and activate the elastomeric component. The application of plasma is controlled to achieve a sufficient surface composition change to enhance adhesion characteristics while not adversely physically deforming the elastomeric component. The plasma treatment is applied to increase carbonyl functional group concentrations within an altered region of the elastomeric component to within at least a range of 2%-15% of carbon atomic percentage composition. The cleaning and activation is controlled, in part, by ensuring a defined height offset range is maintained between the elastomeric component and the plasma source by a generated tool path. The elastomeric component may then be adhered, with an adhesive, to another component.
Plasma assisted hydrophilicity enhancement of polymer materials
A method of enhancing hydrophilicity of a hydrophobic polymer material includes pre-treating the hydrophobic polymer material. The pre-treating includes treating the hydrophobic polymer material with a first atmospheric pressure plasma discharge in a first atmosphere including carbon dioxide to obtain a pre-treated polymer material. The method includes treating the pre-treated polymer material with a second atmospheric pressure plasma discharge in a second atmosphere in which an aerosol of an amine is introduced; the amine includes at least one hydrocarbon substituent. A substrate is provided that includes a hydrophobic polymer material having a modified interface. The modified interface includes amine functional groups grafted on the hydrophobic polymer material, the modified interface having a surface energy, which, measured after immersion in water at 20? C. for 3 days, differs from a surface energy of the hydrophobic polymer material by 20 mN/m or less.
