The present teachings generally provide curable polysiloxane compositions including a base resin including a surface active polymer. Articles of manufacture including the curable polysiloxane compositions and slippery coatings and materials also are provided. The compositions may be used to provide slippery, lubricious, or repellent materials and coatings and may provide anti-fouling function. The compositions can provide anti-fouling or foul-release function on open surfaces, internal surfaces, membranes; to provide pinning free or low contact angle hysteresis surfaces; to provide homogeneous interface to suppress nucleation; to provide a barrier layer such as anti-corrosion; to provide anti-stain, anti-smudge, anti-fingerprint, anti-soil function.

A method of preparing a composite includes providing a porous material including a polymeric network and a polar particle; depositing an ink onto the porous material via a printing process; and delivering a lubricating fluid to the porous material to form a coating. A composite is obtained from the method, and an anti-fouling product including the composite is provided.

Coating compositions, coatings, and coated articles are provided exhibiting drag-reducing properties. The drag reduction can lead to improved flow, e.g. an improved measure of slip length, over both laminar and turbulent flow conditions, e.g. for Reynolds numbers less than 2,000 to as much as about 500,000. The coating compositions include abase matrix and an effluent polymer dispersed in the base resin in such a way that, when an exposed surface of the drag-reducing coating is exposed to an aqueous medium, the effluent polymer migrates to the exposed surface of the drag-reducing coating and into the aqueous medium at or near the exposed surface to create a diluted effluent polymer solution in the aqueous medium at or near the exposed surface; wherein the diluted effluent polymer solution reduces a drag of the surface moving through the aqueous medium.
