KAIST Uses Surface ‘Defects’ to Enhance Droplet Formation and Removal, Achieving Up to 5.5 Times the Heat Transfer Performance of Conventional Surfaces

Caption

Conceptual illustration of the study. A nanoscale polymer film deposited on a copper tube by initiated chemical vapor deposition (iCVD) promotes droplet nucleation during water vapor condensation and facilitates the rapid removal of the resulting droplets. The circular inset shows nanoscale aggregates on the polymer surface that contribute to condensation nucleation.
