example

[0384] Hereinafter, examples of the present invention will be described, but the present invention is not limited by these examples. In addition, "%" and "part" which are content in an example are based on a mass standard.

[0385] In the following examples, the average diameter (average minor axis length) and average major axis length of metal nanowires, the coefficient of variation of minor axis length, and the ratio of silver nanowires with an aspect ratio of 10 or more were measured as follows.

[0386]

[0387] Diameter (minor axis length) and major axis length of 300 randomly selected metal nanowires from among metal nanowires subjected to enlarged observation with a transmission electron microscope (TEM; manufactured by JEOL Ltd., JEM-2000FX) The measurement was performed, and the average diameter (average minor axis length) and the average major axis length of the metal nanowires were obtained from the average values.

[0408]

[0409] Use AA (9.64g), BzMA (35.36g) as the monomer component that constitutes copolymer, use AIBN (0.5g) as radical polymerization initiator, make these carry out polymerization reaction in solvent PGMEA (55.00g), borrow This obtained a PGMEA solution (solid content concentration: 45% by mass) of the binder (A-1). Furthermore, the polymerization temperature is adjusted to a temperature of 60°C to 100°C.

[0410] As a result of measuring the molecular weight by gel permeation chromatography (GPC), the polystyrene-equivalent weight average molecular weight (Mw) was 11000, the molecular weight distribution (Mw / Mn) was 1.72, and the acid value was 155 mgKOH / g.

[0415]

[0416] 7.48 g of MFG (manufactured by Nippon Emulsifier Co., Ltd.) was added to the reaction vessel in advance, and the temperature was raised to 90° C., and then MAA (14.65 g), MMA (0.54 g), CHMA (17.55g), AIBN (0.50g) and the mixed solution of MFG (55.2g) which are radical polymerization initiators were dripped at 90 degreeC reaction container. After the dropwise addition, it was reacted for 4 hours to obtain an acrylic resin solution.

[0417] Then, after adding hydroquinone monomethyl ether 0.15g and tetraethylammonium bromide 0.34g to the obtained acrylic resin solution, GMA12.26g was dripped over 2 hours. After the dropwise addition, it was reacted at 90° C. for 4 hours while blowing air, and then prepared by adding PGMEA so that the solid content concentration became 45%, thereby obtaining a solution of the binder (A-2) (solid content Concentration: 45%).

Abstract

A conductive member containing: a base material; a conductive layer provided on the base material, wherein the conductive layer includes a metallic nanowire having an average short axis length of 150 nm or less and a matrix; and a protective layer including a three-dimensional crosslinked structure represented by the following Formula (I), sequentially in this order, and which has a surface resistivity measured at a surface of the protective layer of 1,000 Omega / □ or less, a production method of the conductive member, and a touch panel and a solar cell, each of which uses the conductive member. The conductive member may provide high resistance against scratches and abrasion, excellent conductivity, excellent transparency, excellent heat resistance, excellent moisture and heat resistance, and excellent bendability. -M1-O-M1-Formula (I): In the Formula (I), M1 represents an element selected from the group consisting of Si, Ti Zr and Al.

Description

technical field [0001] The invention relates to a conductive member, a method for manufacturing the conductive member, a touch screen and a solar cell. Background technique [0002] In recent years, a conductive member having a conductive layer including conductive fibers such as metal nanowires has been proposed (for example, see Japanese Patent Laid-Open No. 2009-505358). This conductive member is a conductive member provided with a conductive layer including a plurality of metal nanowires on a substrate. This conductive member can be easily processed to have a desired conductive region and The conductive member of the conductive layer in the non-conductive region. This processed conductive member can be used, for example, as a touch panel or as an electrode of a solar cell. [0003] The film strength of the conductive layer of the above-mentioned conductive member is weak. Therefore, it has also been proposed to provide a hard film on the surface of the conductive lay...
