Wet and dry? The ability to control wettability of a solid surface is essential in many fields. A simple and effective “template rolling press” method for preparing large-area patterned surfaces with controlled wetting properties (see picture) on the nanometer scale is demonstrated. It is believed that reorientation of polymer molecules occurs when the polymer is heated and compressed into the nanopore of the template.
