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.
