Abstract

A cure-activated nanolayer transfer technique is described, which when combined with soft imprinting (lithography) can be used to fabricate multiple surface-functionalized replicas from the same mould without the need for a separate secondary functionalization step. For instance, the hierarchical roughnesses of plant leaves and moth wings are successfully replicated to yield superhydrophobicity. The inherent simplicity and nanometer-scale precision of this approach makes it highly attractive for a plethora of surface-functionalization and patterning applications.
