Generically referred to as 3-dimensional applications, this new frontier is now being perused by researchers who are working to create 3-D structures made entirely of Parylene. Additionally, SCS Parylene coatings are optically clear, so the coating does not reduce the color or lumens output of the LEDs. In this Section: Coatings of parylene are often applied to electronic circuits and other equipment as electrical insulation, moisture barriers, or protection against corrosion and chemical attack ( conformal coating ). 12a–c, the interconnection of neighboring nanowires increases as the length of nanowires increases, and they were interconnected before the parylene coating. Parylene coating applications take place inside a chemical vapor deposition (CVD) vacuum system, where the products wait inside a room-temperature chamber.
