Porous nanomaterials having three-dimensional patterning

Abstract

Provided are methods for imprinting a porous material, the methods including applying a first stamp to a porous material having an average pore size of less than about 100 μm, the first stamp having at least a first portion having a first height, a second portion having a second height and a third portion having a third height, wherein the first height, second height and third height are different.
