Sustained polymer membranes fabricated by nanoimprint lithography

摘要

Perforated polymer membranes are fabricated using nanoimprint lithography and a sacrificial layer technique. The membranes with micrometer-sized pores are partially released from the substrate by locally dissolving the underlying layer. Thus, large arrays with interconnected pores can be fabricated. This process can be applied to a wide selection of polymeric materials, and has the potential to be extended to sbmicrostruCtures.
