Functional Nanoimprinting

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. Full Paper: A cure activated nanolayer transfer technique is devised, 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. This has been exemplified for the hierarchical roughnesses of plant leaves and moth wings to yield superhydrophobicity.
