Microstructured material and process for its manufacture

A process for making the microstructured article of claim 1 comprising:

• a) forming a network of interconnected traces comprising nanoparticles surrounding randomly-shaped cells on the surface of a substrate by self assembly of the nanoparticles from an emulsion;
• b). electroplating the network;
• c) exposing the network to an acid to release the network from the substrate;
• and
• d) removing the network from the substrate.

A process for making the microstructured article of claim 1 comprising:

• a) forming a network of interconnected traces comprising nanoparticles surrounding randomly-shaped cells on the surface of a substrate by self assembly of the nanoparticles from an emulsion;
• b) separating the network from the substrate by mechanical means;
• and
• c) collecting the separated network on a roll.
