Abstract
A composite layer including first and second layers is described. The first layer includes a plurality of metallic nanowires and the second layer includes a polymeric overcoat disposed on the nanowires. In top plan view, the composite layer has at least one first region and at least one second region, where the nanowires in each first region form an interconnected network of the nanowires, and each second region includes a plurality of nanotrenches through the second layer into the first layer.
Claims20
A composite layer comprising:
- a first layer comprising a plurality of metallic nanowires;
- a second layer comprising a polymeric overcoat disposed on the nanowires,
- wherein, in top plan view, the composite layer has at least one first region and at least one second region, the nanowires in each first region forming an interconnected network of the nanowires, each second region comprising a plurality of nanotrenches through the second layer into the first layer.
A composite layer comprising at least one first region and at least one second region, each first and second region comprising a plurality of metallic nanowires and a polymeric overcoat disposed on the nanowires, the nanowires in each first region forming an interconnected network of the nanowires, each second region comprising a plurality of nanotrenches such that each second region has an electrical resistivity of at least 1000 times an electrical resistivity of a first region.
A composite layer comprising at least one first region and at least one second region, each first and second region comprising a plurality of metallic nanowires and a polymeric overcoat disposed on the nanowires, the nanowires in each first region forming an interconnected network of the nanowires, each second region comprising a plurality of nanotrenches free of nanowires, each nanotrench replacing a segment of an otherwise continuous nanowire.
