Methods for plasma depositing polymers comprising cyclic siloxanes and related articles and compositions are generally provided. In some embodiments, the methods comprise flowing a precursor gas in proximity to a substrate within a PECVD reactor, wherein the precursor gas comprises an initiator and at least one monomer comprising a cyclic siloxane and at least two vinyl groups, and depositing a polymer formed from the at least one monomer on the substrate.

Systems having one or more features that are advantageous for depositing fluorinated polymeric coatings on substrates, and methods of employing such systems to deposit such coatings, are generally provided.

Systems and methods for polymer deposition

Systems, methods, and articles for polymer deposition

Methods and systems for polymer deposition

Coated articles and methods and systems for coating the articles are described herein. The methods and systems described herein include, but are not limited to, steps for actively or passively controlling the temperature during the coating process, steps for providing intimate contact between the substrate and the support holding the substrate in order to maximize energy transfer, and/or steps for preparing gradient coatings. Methods for depositing high molecular weight polymeric coatings, end-capped polymer coatings, coatings covalently bonded to the substrate or one another, metallic coatings, and/or multilayer coatings are also disclosed. Deposition of coatings can be accelerated and/or improved by applying an electrical potential and/or through the use of inert gases.

Methods for coating articles

Electrowetting devices coated with one or more polymeric layers and methods of making and using thereof are described herein. The coatings may be formed in a single layer or as multiple layers. In one embodiment the first layer deposited serves as an insulating layer of high dielectric strength while the second layer deposited serves as a hydrophobic layer of low surface energy. These materials may themselves be deposited as multiple layers to eliminate pinhole defects and maximize device yield. In one embodiment the insulating layer would be a vapor deposited silicone polymeric material including, but not limited to, polytrivinyltrimethylcyclotrisiloxane or polyHVDS. In another embodiment the insulating layer may be a vapor deposited ceramic such as SiOwith very little carbon content. In a further embodiment the insulating layer may be composed of alternating layers of a siloxane material and a ceramic material.
