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.
