Abstract
A slide coating apparatus for coating liquid with a first slide member having a first slide surface onto which a first liquid may flow, and a second slide member having a second slide surface over which the first liquid may flow, the first slide member being positioned relative to the second slide member to form a first slot through which the first liquid may flow before flowing over the second slide surface, the first slide surface being positioned relative to the second slide surface such that at least a portion of the first liquid flowing from the first slot may flow onto the first slide surface rather than to flow directly from the first slot over the second slide surface, the first slide surface having a low surface energy region positioned such that it may come in contact with the first liquid.
