Synthesis and Self-Assembly of Large-Area Cu Nanosheets and Their Application as an Aqueous Conductive Ink on Flexible Electronics
Large-area Cu nanosheets are synthesized
by a strategy of Cu nanocrystal
self-assembly, and then aqueous conductive Cu nanosheet ink is successfully
prepared for direct writing on the conductive circuits of flexible
electronics. The Cu nanocrystals, as building blocks, self-assemble
along the ⟨111⟩ direction and grow into large-area nanosheets
approximately 30–100 μm in diameter and a few hundred
nanometers in thickness. The laminar stackable patterns of the Cu
nanosheet circuits increase the contact area of the Cu nanosheets
and improve the stability of the conductor under stress, the result
being that the Cu nanosheet circuits display excellent conductive
performance during repeated folding and unfolding. Moreover, heterostructures
of Ag nanoparticle-coated Cu nanosheets are created to improve the
thermal stability of the nanosheet circuits at high temperatures
