This paper examines a new approach for synthesizing Parylene-metal multilayers. The metal layers are obtained from a metal salt solution and a plasma reduction treatment. This one-pot synthesis process requires less resources and energy compared to electron beam sputtering processes. The Parylene coatings are obtained after plasma treatments with Parylene C. The process provides ultra-thin metal salt layers and Parylene layers with good tensile strength and wettability.
In this paper, a new approach for the synthesis of Parylene-metal multilayers was examined. The metal layers were derived from a metal salt solution in methanol and a post-drying plasma reduction treatment. This process was designed as a one-pot synthesis, which needs a very low amount of resources and energy compared with those using electron beam sputtering processes. The Parylene coatings were obtained after reduction plasma treatments with Parylene C. Therefore, a Parylene coating device with an included plasma microwave generator was used to ensure the character of a one-pot synthesis. This process provided ultra-thin metal salt layers in the range of 1-2 nm for layer thickness and 10-30 nm for larger metal salt agglomerates all over the metal salt layer. The Parylene layers were obtained with thicknesses between approx. 4.5 and 4.7 mu m from ellipsometric measurements and 5.7-6.3 mu m measured by white light reflectometry. Tensile strength analysis showed an orthogonal pulling stress resistance of around 4500 N. A surface roughness of 4-8 nm for the metal layers, as well as 20-29 nm for the Parylene outer layer, were measured. The wettability for non-polar liquids with a contact angle of 30 degrees was better than for polar liquids, such as water, achieving 87 degrees on the Parylene C surfaces.
