MICROCONTACT PRINTING STAMPS WITH FUNCTIONAL FEATURES

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.

1. A method comprising:
providing an elastomeric stamp comprising a base surface and a stamping surface extending away from the base surface, the stamping surface comprising at least one first pattern element and at least one second pattern element, and wherein:
the first pattern element of the stamping surface has a fill factor of 20 to 99 percent, and the first pattern element of the stamping surface comprises a continuous region and at least one discontinuous region comprising at least one of: (1) one or more elongated concavities, and (2) one or more interior voids; andthe second pattern element of the stamping surface has a fill factor of 0.25 to 10 percent, and the second pattern element of the stamping surface comprises traces with a width from 0.1 micrometers to 50 micrometers;inking the stamping surface with an ink composition comprising a functionalizing molecule with a functional group selected to bind to a surface of the ink-receptive material; andcontacting the inked stamping surface with a major surface of the 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 thereon.
