Abstract: Provided is a method of patterning a substrate. The method includes depositing, in a first predetermined pattern, hydrophobic material on a first surface of a hydrophilic substrate. The method includes permeating the hydrophobic material through a thickness of the substrate without reflowing the deposited hydrophobic material. The method includes sufficiently solidifying the permeated hydrophobic material. The sufficiently solidified hydrophobic material forms a liquid-impervious barrier that separates the substrate into at least one discrete region.

Abstract: A polymer composition includes a first polymer layer containing a base polymer matrix, and a second polymer layer grafted onto the first layer. The second polymer layer contains a stimulus-responsive polymer, and the surface free energy of the stimulus-responsive polymer is adjustable from a first surface free energy state to a second surface free energy state when heated to a critical activation temperature. A method of preparing a polymer composition includes providing a first polymer layer containing a base polymer, and grafting a second polymer layer containing a stimulus-responsive layer onto the first layer. A method of printing an image involves applying an ink onto an intermediate transfer member containing a first polymer layer containing a base polymer matrix and a second polymer layer containing a stimulus-responsive polymer grafted onto the first layer, spreading the ink, inducing a property change of the ink, and transferring the ink to a substrate.

Abstract: A method and structure for a device including a non-contact gap control device for maintaining a distance between surfaces can include a pliable platform, a frame to which the pliable platform is secured, an aerodynamic floating (AF) head attached to the pliable platform and a probe for measuring, testing, and/or characterizing a substrate adjacent to the AF head. A pressurized gas source can be coupled to the AF head, such that a pressurized gas is ejected onto the substrate to maintain a distance between the substrate and the AF head during measurement. While the frame can be held immobile, the pliable platform can react in response to irregularities in the substrate to maintain a generally constant distance between the AF head and the substrate.
