Abstract

Superhydrophobic porous surfaces with hydrophilic polymers adsorbed in pores are designed to control the coalescing behavior of microdroplets as well as their quick self-removal. The combination of chemical composition and surface structure are greatly important in the design of new materials for heat exchange, antifogging, and anti-icing.
