摘要:
A method includes providing an elastomeric stamp including a stamping surface with a first pattern element having a fill factor of 20 to 99 percent and including a continuous region and at least one discontinuous region, the discontinuous region including at least one of: (1) one or more elongated concavities, and (2) one or more interior voids. A second pattern element of the stamping surface has a fill factor of 0.25 to 10 percent, and includes traces with a width from 0.1 micrometers to 50 micrometers. The stamping surface is inked with an ink composition including a functionalizing molecule with a functional group selected to bind to a surface of the ink-receptive material. The inked stamping surface is contacted with an ink-receptive material selected from a sheet or a web for a contact time sufficient to bind the functional group with the surface of the ink-receptive material to form a self-assembled monolayer (SAM) of the functionalizing material.
