Creation of Superhydrophobic and Superhydrophilic Surfaces on ABS Employing a Nanosecond Laser
A nanosecond green laser was employed to obtain both superhydrophobic and superhydrophilic surfaces on a white commercial acrylonitrile-butadiene-styrene copolymer (ABS). These wetting behaviors were directly related to a laser-induced superficial modification. A predefined pattern was not produced...
