Abstract
Official abstract text for this publication.
The method for manufacturing a silver particle-containing composition according to the invention is directed to a method for manufacturing a silver particle-containing composition coated with a fatty acid and includes a step (A) of preparing silver particles coated with a first fatty acid (a) with 3 to 7 carbon atoms, a second fatty acid (b) with 2 to 20 carbon atoms, and a solvent in which the first and second fatty acids can disperse, respectively, a step (B) of adding the silver particles coated with the first fatty acid (a) and the second fatty acid (b) into the solvent, and a step (C) of substituting the second fatty acid (b) for the first fatty acid (a) coating the silver particles after the addition step.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing a silver particle-containing composition coated with a fatty acid, comprising the steps of: preparing silver particles coated with a first fatty acid (a) as sorbic acid, a second fatty acid (b) as butanoic acid, octanoic acid, hexanoic acid, malonic acid, sorbic acid, lactic acid, acetic acid, propionic acid, decanoic acid, oleic acid, malic acid, acetylsalicylic acid, or cholic acid, and isopropyl alcohol as a solvent in which the first and second fatty acids can disperse, respectively; adding the silver particles coated with the first fatty acid (a) and the second fatty acid (b) into the solvent; and substituting the second fatty acid (b) for the first fatty acid (a) coating the silver particles after the addition step. 2. The method for manufacturing the silver particle-containing composition according to claim 1 , wherein the substituting step includes the steps of: agitating the silver particles coated with the first fatty acid (a) and the second fatty acid added in the solvent; and subjecting the solvent to an ultrasonic vibration process with ultrasound after the agitating step. 3. The method for manufacturing the silver particle-containing composition according to claim 1 , wherein the second fatty acid (b) is lactic acid. 4. A method for manufacturing a silver particle-containing composition coated with a fatty acid, comprising the steps of: preparing silver particles coated with a first fatty acid (a), a second fatty acid (b), and isopropyl alcohol as a solvent in which the first and second fatty acids can disperse, respectively; adding the silver particles coated with the first fatty acid (a) and the second fatty acid (b) into the solvent; and substituting the second fatty acid (b) for the first fatty acid (a) coating the silver particles after the addition step, wherein the number of carbon atoms of the first fatty acid (a) is 6 and the number of carbon atoms of the second fatty acid (b) is 3.
