Water, ice, and surface contamination are significant problems in various industries including transportation, power, buildings, and consumer products. For example, ice accumulation can reduce the performance of aircraft and solar panels.

Hydrophobic surfaces are sometimes used to reduce the water and ice accumulation. However, conventional superhydrophobic surface structures are passive structures and generally relatively delicate structures.

Boeing’s superhydrophobic surface structures are actively-controlled surface structures exhibiting a superhydrophobic state and an ordinary state. They use MEMS (micro-electro-mechanical system) actuators to activate the superhydrophobic surface.

This technology will increase the safety of aircraft and also add some years to the their life
