Title: METHOD FOR PROVIDING AN AGGREGATE OF ALIGNED NANOWIRES AT A LIQUID-LIQUID INTERFACE
Abstract:
A method for forming an aggregate of assembled aligned nanowires (20), wherein said nanowires comprise an elongate wire portion (21) and a head portion (23) at a first end of the elongate wire portion, comprising providing a fluid comprising a first liquid (11), a second liquid (12) and a plurality of nanowires, wherein the first and second liquids phase separate into a first phase, a second phase, and an interface (13) between the first and second phases; wherein the nanowires are functionalized to align vertically and assemble into a nanowire aggregate at the interface, with said wire portion in the first phase and said head portion in the second phase; providing a dielectric coat (22) to the nanowires, providing a first bonding substance (22A) to the first phase and a second bonding substance (41) to the second phase; bonding the nanowires of the nanowire aggregate using said substances.
