Abstract: A highly stretchable superhydrophobic thin film using initiated chemical vapor deposition is prepared by a method in which a substrate is coated with a copolymer at a nanometer thickness by allowing a fluorine monomer containing 4 to 6 fluoroalkyl groups and having a glass transition temperature of 5° C. or less to react with a crosslinking monomer on the substrate in the presence of an initiator in an initiated chemical vapor deposition reactor and thus its durability can be secured in foldable and wearable devices.

Abstract: A method of preparing a material having a superhydrophobic region and a hydrophobic region is described, involving preparing a superhydrophobic surface body and hydrolyzing one surface of the prepared superhydrophobic surface body using a strong base. Such preparation method is simpler than conventional preparation methods and is capable of preparing a material having opposite surface characteristics at low costs.
