“…While this mode which is known as filmwise condensation 14 ( Figure 1a) is quite common, the formation of a liquid film is not desired due to the large resistance to heat transfer. Meanwhile, if a surface is coated with a low-energy non-wetting 'promoter' material (i.e., long chain fatty acid, wax, polymer coating, self-assembled monolayer) [15][16][17][18][19] , or if it naturally adsorbs hydrocarbons and impurities on its surface from the surroundings (as in the case of gold, silver, and chromium) [20][21][22] , the vapor forms discrete liquid droplets ranging in size from microns to millimeters [23][24][25] . This process is known as dropwise condensation 26 ( Figure 1b).…”

(150 words max)Condensation is a phase change phenomenon often encountered in nature and industry for applications including power generation, thermal management, desalination, and environmental control. For the past eight decades, researchers have focused on creating surfaces allowing condensed droplets to be easily removed by gravity for enhanced heat transfer performance.Recent advancements in nanofabrication have enabled increased control of surface structuring for the development of superhydrophobic surfaces with even higher droplet mobility, and in some cases, coalescence-induced droplet jumping. Here, we provide a review of new insights gained to tailor superhydrophobic surfaces for enhanced condensation heat transfer considering the role of surface structure, nucleation density, droplet morphology, and droplet dynamics.Furthermore, we identify challenges and new opportunities to advance these surfaces for broad implementation into thermo-fluidic systems.

“…Laboratory studies have shown that hydrophobic and superhydrophobic surfaces improve heat-transfer rates by promoting dropwise condensation over fi lm condensation. 23 The benefi ts of higher heattransfer coeffi cients would be accrued mainly through cost savings due to smaller heat exchangers. Savings in water use …”

“…Up to the 1990s, numerous dropwise condensation studies were conducted with a thin layer of a metal-organic compound or low-surface-fee-energy polymer coated flat surfaces. [80,107,108,109]. For instance, Marto et al [107] examined several polymer coatings in terms of their ability to promote and sustain dropwise condensation of steam.…”

“…[80,107,108,109]. For instance, Marto et al [107] examined several polymer coatings in terms of their ability to promote and sustain dropwise condensation of steam. They contended that the organic coatings were successful in promoting good quality dropwise condensation for prolonged periods of times (> 12,000 h).…”
