Abstract
A hydrophobic coating and method of preparing a hydrophobic coating with an adhesion promoting layer formed from an adhesion promoting composition and a hydrophobic layer, is disclosed. The adhesion promoting composition may comprise an adhesion promoting compound having an amine group and at least one of a silane functional group and/or a germanium functional group. The hydrophobic layer forming composition may comprise a hydrophobic layer forming compound having a hydrophobic aliphatic group and at least one of a silane functional group and/or a germanium functional group.
Claims1
A method comprising;
- treating a polymeric surface with plasma;
- exposing the treated surface in the vapor phase to an adhesion promoting compound, the adhesion promoting compound having at least one silane functional group and at least one amine group to form an amino silane coated surface;
- attaching an alkoxy silane selected from one or more of methoxy and ethoxy silanes by reacting the alkoxy silane in the vapor phase with the amino silane coated surface to form a hydrophobic outer surface, the alkoxy silane having at least one terminal —CF3 group and at least 3 —CF2— groups, and at least one —CH2—CH2— group.
