1. A method for treating a surface of an article in order to increase the hydrophobic characteristics of the surface, comprising:
- (a) providing one or more surfaces; and
(b) exposing the surface to an ionizing gas plasma at about atmospheric pressure for a predetermined period of time, the ionizing gas plasma being formed from a gas mixture comprising a carrier gas and a reactive gas.

Abstract
A method for increasing the hydrophobic characteristics of a surface. The surface is exposed to an ionizing gas plasma at about atmospheric pressure for a predetermined period of time. The ionizing gas plasma is formed from a mixture of a carrier gas and a reactive gas. The reactive gas may be comprised of one or more hydrocarbon compound such as an alkane, an alkene, and an alkyne. Alternatively, the reactive gas may be a fluorocarbon compound.
