Waterborne films and coatings, and more particularly, superhydrophobic films and coatings have gained considerable attention in recent years due to a number of attractive qualities. Highly hydrophobic surfaces have been recognized in nature, perhaps most commonly on lotus leaves and cicada wings. Due to its hydrophobic nature, lotus leaves are able to self-clean by washing away dust particles and debris as the water droplets roll off their surface. This ability to automatically clean is desirable in many modern applications. But the existing preparation method of the super-hydrophobic membrane has higher cost.
