Method for microstructing polymer-supported materials
View Patent ↗A method is provided for microstructuring polymer-supported materials. Also provided are microstructured objects obtained with this method. The microstructured objects are suitable for use, among other things, as light polarizers, transflectors, microelectrode arrays, and liquid-crystal alignment layers.
1. A process of forming an array of microelectrodes comprising:
pressing a master into a multi-layered structure,
said master having a surface facing said multi-layered structure, said surface comprising an area having a protruding micro-structured pattern comprising tapered features defining protruding edges,
said multi-layered structure comprising at least one supporting layer that entirely remains in the solid state during pressing, and formed directly on said supporting layer, and positioned between said master and said at least one supporting layer, a metal layer,
wherein at least said edges of said tapered features of said micro-structured pattern penetrate through said metal layer into said at least one supporting layer, so as to form an array of microelectrodes.
