Abstract
Conductive patterns and methods of using and printing such conductive patterns are disclosed. In certain examples, the conductive patterns may be produced by disposing a conductive material between supports on a substrate. The supports may be removed to provide conductive patterns having a desired length and/or geometry.
Claims6
A device comprising at least one high-aspect ratio conductive pattern disposed thereon, wherein the device comprises a substrate and wherein the high aspect ratio conductive pattern is produced by:
- a. disposing a support layer on the substrate defining a spacing having an effective height;
- b. disposing a conductive material between the defined spacing of the support layer, wherein the conductive material comprises metal particles, said metal particles comprising a metal or a metal salt capped with a capping agent, wherein the capping agent has a molecular weight of at least about 100 g/mol;
- and
- c. removing the support;
- wherein further support layers can be disposed followed by disposing of additional conductive material to increase the effective height of the high aspect ratio conductive pattern, prior to removing the support.
