An Introduction to Superhydrophilic and Superhydrophobic Surfaces

Aside to their contrary nature, both superhydrophilic and superhydrophobic surfaces show self-cleaning effect. Now almost all of superhydrophilic surfaces comprise titanium dioxide photocatalyst, and a lot of superhydrophobic surfaces are fluorocarbon-based materials. Both chemical nature and nanoscale unflatness of a surface affect its superhydrophobicity. Some more recent articles and patents in the field of superhydrophilic and superhydrophobic surfaces have been reviewed.
