preparation example 1

[0572] -Preparation of silver nanowire dispersion (1)-

[0573] Additive solutions A, B, C, and D described below were prepared in advance.

[0574] [additive solution A]

[0575] 120 mg of stearyltrimethylammonium chloride, 12.0 g of a 10% aqueous solution of stearyltrimethylammonium hydroxide, and 4.0 g of glucose were dissolved in 240.0 g of distilled water to prepare a reaction solution A-1. Further, 140 mg of silver nitrate powder was dissolved in 4.0 g of distilled water to prepare silver nitrate aqueous solution A-1. The reaction solution A-1 was kept at 25°C, and the silver nitrate aqueous solution A-1 was added with vigorous stirring. Vigorous stirring was performed for 180 minutes after the addition of the silver nitrate aqueous solution A-1 to prepare an addition liquid A.

[0576] [additive solution B]

[0577] 42.0 g of silver nitrate powder was dissolved in 958 g of distilled water.

[0578] [additive liquid C]

[0579] Mix 75 g of 25% ammonia water and 925...

preparation example 2

[0586] -Preparation of silver nanowire dispersion (2)-

[0587] In preparation example 1, except having used 125.0 g of distilled water instead of additive liquid A, it carried out similarly to preparation example 1, and obtained the silver nanowire dispersion liquid (2) whose metal content was 0.47%.

[0588] For the silver nanowires in the obtained silver nanowire dispersion (2), the average minor axis length, the average major axis length, the coefficient of variation of the minor axis length of the silver nanowires, and the average aspect ratio were measured as described above. As a result, the average minor axis length was 47.0 nm, the average major axis length was 13.0 μm, and the coefficient of variation was 22.9%. The average aspect ratio is 277. Hereinafter, when described as "silver nanowire dispersion liquid (2)", it means the silver nanowire dispersion liquid obtained by the above-mentioned method.

preparation example 3

[0590] -Preparation of silver nanowire dispersion (3)-

[0591] Silver nitrate solution 301 was prepared by dissolving 60 g of silver nitrate powder in 370 g of propylene glycol. 72.0 g of polyvinylpyrrolidone (molecular weight: 55,000) was added to 4.45 kg of propylene glycol, and the temperature was raised to 90° C. while blowing nitrogen into the gas phase portion of the container. The obtained solution was referred to as a reaction solution 301 . Under the condition of maintaining nitrogen ventilation, 2.55 g of silver nitrate solution 301 was added to the vigorously stirred reaction solution 301, and heated and stirred for 1 minute. Further, a solution obtained by dissolving 11.8 g of tetrabutylammonium chloride in 100 g of propylene glycol was added to this solution to prepare a reaction solution 302 .

[0592] 200 g of the silver nitrate solution 301 was added at an addition rate of 50 ml / min to the reaction solution 302 kept at 90° C. and stirred at a stirring rate o...

Description

【Technical field】 [0001] The present invention relates to a conductive composition, a conductive member, a method for producing the conductive member, a touch panel, and a solar cell. 【Background technique】 [0002] In recent years, touch panels are mounted on display devices such as liquid crystal panels and electronic paper as input devices. Various configurations such as a resistive film method, a surface acoustic wave method, and an electrostatic capacitance method are known as the configuration of a touch panel. As a method capable of multi-touch and easy to increase the area, an electrostatic capacitance method is known. Capacitive touch panel using ITO (Indium Tin Oxide), which is a transparent conductive material. [0003] However, the price of indium as an ITO raw material is expensive, and its stable supply is limited; a vacuum process is required in thin film production, so the manufacturing cost is high; and the ITO film has problems of brittleness and poor bend...
