Transparent conductor using silver nanowires to improve haze and electrical conductivity

Abstract

The invention relates to a transparent conductor, comprising a conductive layer, wherein on the transparent substrate thereof, a plurality of silver nanowires with the average diameter of 15-22 nm, and average length of 10-20 mu m are combined through an adhesive to form a conductive network; and a protection layer formed on the conductive layer. Accordingly, the transparent conductor has excellent transparency, conductivity and haze.

Description

Technical field [0001] The present invention relates to a transparent conductor, and relates to a transparent conductor using silver nanowires with excellent electrical and optical properties. Background technique [0002] Recently, transparent conductors have been widely used in touch panels, liquid crystal displays, organic light emitting diode devices, and thin film photovoltaic cells. A representative transparent conductive conductor is an ITO substrate. [0003] However, metal oxide conductors like ITO have complicated reaction engineering. In order to achieve higher conductivity, deposition of a thick oxide layer requires high-temperature annealing (annealing). Therefore, it has the shortcomings of low transmittance and no flexibility. [0004] Therefore, a transparent conductor based on silver nanowires with high conductivity, excellent light transmittance and flexibility is being developed and mass-produced recently. [0005] The existing transparent conductors based on silv...
