Abstract
A method for manufacturing an electrically-conductive paste includes: bringing carbon nanotubes (CNT) and a solvent into contact with each other so that a wetting rate is 25 to 125%; kneading, by using a planetary stirring machine, a mixture containing the CNT and the solvent obtained by impregnating the CNT with the solvent, to obtain a kneaded product in a paste state; and then performing dispersion processing on a dilution obtained by mixing a solvent into the obtained kneaded product.
Claims4
A method for manufacturing an electrically-conductive paste, the method comprising:
- bringing carbon nanotubes (hereinafter, referred to as “CNT”) and a solvent into contact with each other so that a wetting rate represented by a formula (1) below is 25 to 125%;
- kneading, by using a planetary stirring machine, a mixture containing the CNT and the solvent, to obtain a kneaded product in a paste state, the mixture being obtained by impregnating the CNT with the solvent;
- and
- performing dispersion processing on a dilution obtained by mixing a solvent into the kneaded product obtained, wherein
- the wetting rate (%)=A/B×100 (1),
- where A is a concentration of the CNT, when the solvent has penetrated to a maximum extent, and is calculated by a formula below,
- A (%)=1 g of the CNT/(1 g of the CNT+a maximum penetration weight [g] of the solvent per 1 g of the CNT)×100, and
- B is a concentration of the CNT in the mixture, and is calculated by a formula below,
- B (%)=a weight of the CNT[g]/a weight of the mixture [g]×100.
