Abstract
Provided is a novel printing process for fabricating metallic, conductive and transparent ultra-thin nanowires and patterns including same on a substrate. The process includes two different controllable steps, each designed to achieving a useful and efficient pattern.
Claims13
A process for forming a transparent and conductive metal nanowire film on a surface region of a substrate, the process comprising:
- (a) applying on at least one surface region of a substrate a solution comprising metal seeds;
- (b) applying a growth solution on the at least one surface region, wherein the growth solution comprises at least one metal reducing agent, and at least one surfactant, and wherein the growth solution is free of metal seeds;
- and
- (c) allowing formation of a metal nanowire film in a region where both the solution comprising metal seeds and the growth solution have been applied,
- wherein said solution comprising metal seeds or said growth solution further comprises at least one metal precursor, wherein the metal seeds and the at least one metal precursor are of the same metal element;
- and
- wherein the metal nanowire film comprises a plurality of metal nanowires formed in said the at least one surfactant.
