Description

field of invention

[0001] The present invention relates to anticorrosion agents for transparent conductive films comprising a random network of silver nanowires and a polymeric binder, and to methods of making and using films containing these anticorrosion agents. Background of the invention

[0002] Transparent conductive films (TCFs) have been widely used in recent years for various applications such as touch panel displays, liquid crystal displays, electroluminescent lighting, organic light emitting diode devices, and photovoltaic solar cells. Due to high conductivity, transparency and relatively good stability, transparent conductive films based on indium tin oxide (ITO) have been the most widely used transparent conductors. However, ITO-based transparent conductive films have limitations due to the high cost of indium, the need for complex and expensive vacuum deposition equipment and methods, and the inherent brittleness and tendency of ITO to break, especially when it...

Embodiment Construction

[0037] definition:

[0038] The term "conductive layer" or "conductive film" refers to a network layer comprising silver nanowires dispersed in a polymeric binder.

[0039] The term "conductive" refers to electrical conductivity.

[0040] The term "article" refers to a coating of a "conductive layer" or "conductive film" on a support.

[0041] The terms "coating weight", "coat weight" and "coverage" are synonymous and are usually expressed in weight or moles per unit area, such as g / m 2 or mol / m 2 .

[0042] The term "transparent" means capable of transmitting visible light without significant scattering or absorption.

[0043] "Haze" is the large angle scattering that spreads the light evenly in all directions. It is the percentage of transmitted light that deviates from the incident light by more than an average of 2.5 degrees. Haze reduces contrast and produces a milky or hazy appearance. The lower the Haze value, the less blurry the material.

[0044] The term "org...
