Durable superhydrophobic components have a superhydrophobic material disposed (e.g., disposed) thereon that exhibits an apparent advancing dynamic contact angle of &#x2265;about 150&#xb0; and a roll-off angle of about &#x2264;15&#xb0; for water after at least 100 abrasion cycles. The superhydrophobic material may comprise a low surface energy material and a polymeric material. The superhydrophobic material may be self-healing and capable of recovering its wettability after damage. In yet other aspects, a component comprises a surface that is superhydrophobic and reduces drag in turbulent flow conditions. The surface has an apparent advancing dynamic contact angle of &#x2265;about 150&#xb0; and a roll-off angle of &#x2264;about 15&#xb0; for water, and a product of dimensionless roughness (k) and a higher-pressure contact angle hysteresis of less than or equal to about 5.8. Methods of making such materials are also provided.
