Abstract

The present invention provides a method of producing a substrate comprising a porous network. The method comprises forming a substrate precursor containing an array of template particles; and removing the template particles from the substrate precursor using a solvent at a temperature below room temperature to yield the substrate. The present invention also provides a method of producing a substrate comprising a first porous network and a second porous network, the two porous networks being interconnected. The method comprises: forming a substrate precursor containing an array of first template particles and an array of second template particles; selectively removing the first template particles from the substrate precursor to form the first porous network; and subsequently removing the second template particles from the substrate precursor to form the second porous network.
