Abstract
Coatings for reducing or preventing fouling of surfaces are provided. In some embodiments, the coating comprises a silane compound, a siloxane compound, a phosphonate compound, a silicone polymer such as PDMS (polydimethylsiloxane), or a combination of silane-siloxane-phosphonate-PDMS in various molecular configurations in single monolayer and overlay assemblies. Also provided are related methods for forming the coating as well as coated substrates such as heat exchangers. Embodiments of the coatings are highly hydrophobic with high contact angles and the coated substrates may be used in a variety of industrial applications that require handling of oil-in-water emulsions, process water and produced water from various process operations, including Steam Assisted Gravity Drainage (SAGD) operations.
