Abstract:
A conductive nanowire film based on a high aspect-ratio metal is disclosed. The nanowire film is produced by inducing metal reduction in a concentrated surfactant solution containing metal precursor ions, a surfactant and a reducing agent. The metal nanostructures demonstrate utility in a great variety of applications.
Abstract:
Methods for gravure printing of transparent conductive films comprising metal nanowires. Such films exhibiting low resistivity and superior coating uniformity may be used in electronic or optical articles. When the gravure cell opening size approches the average wire length distribution, the gravure cells can behave like an effective filter that allows only small amounts of short wires to be incorporated into the grooves. Use of gravure cells with larger cell opening sizes can allow nanowires to enter gravure cells without such severe skewing of the wire size distribution in the cells.

Abstract:
A system for in-process orientation of particles used in direct-write inks for fabricating a component may include a device for polarizing direct-write particles in an aerosol. An outlet may direct the aerosol including the polarized direct-write particles on a substrate to form a component. An apparatus may cause the polarized direct-write particles to be aligned in a selected orientation to form the component with predetermined characteristics when deposited on the substrate.
