AI Technical Summary
Technical Problem
Parylene coatings exhibit limited application range and weak bonding strength with substrates due to uniform surface energy and reliance on intermolecular van der Waals forces rather than chemical bonding.
Method used
A composite coating comprising Coating I, formed by plasma-polymerizing a substrate with a monomer containing active functional groups, and Coating II, a parylene coating deposited on Coating I, enhancing bonding strength and application range.
Benefits of technology
The composite coating improves the bonding strength and coverage of parylene on substrates, expanding its application range and ensuring robust adhesion.

Abstract
A specific embodiment of the present invention provides a composite coating, manufacturing method, and device, comprising Coating I and Coating II, where Coating I is formed by plasma polymerization of a silane monomer containing an active functional group having affinity or reactivity with polymer molecules and a hydrolyzable group such as a halogen atom, an alkoxy group, or an acyloxy group, and Coating II is formed by vacuum vapor deposition of parylene on Coating I, and the composite coating improves the bonding strength and coverage of the parylene coating to the substrate.
