Abstract
The present invention provides multilayer polymer films, materials and coatings which exhibit robust underwater superoleophobicity and have remarkable structural functional tolerance to a broad range of physical, chemical, and environmental challenges encountered by surfaces deployed in aqueous or aquatic environments. These materials can be fabricated on surfaces of arbitrary shape, size, and composition and provide straightforward means to manipulate surface chemistry and fine-tune other useful features of the interfacial behavior (e.g., underwater oil-adhesiveness). These materials address key obstacles to the application of non-wetting surfaces and anti-fouling ‘super-phobic’ materials in practical, real-world scenarios.
