Title:
ELECTROMAGNETIC WAVE SHIELD SHEET MANUFACTURING METHOD AND ELECTROMAGNETIC WAVE SHIELD SHEET
Document Type and Number:
WIPO Patent Application WO/2021/199649
Kind Code:
A1
Abstract:
Provided is an electromagnetic wave shield sheet manufacturing method by which an electromagnetic wave shield sheet that has a high shielding performance against electromagnetic waves and that is low cost is manufactured. This electromagnetic wave shield sheet manufacturing method comprises: a step for producing a dispersion liquid containing carbon nanotubes, an inorganic pigment, carboxymethyl cellulose, and water; and a step for drying the dispersion liquid. In the dispersion liquid, the ratio of the mass of the inorganic pigment to the mass of the carbon nanotubes is from 1/4 to 1, inclusive.
