Title:
CARBON FILM
Document Type and Number:
WIPO Patent Application WO/2021/172141
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a carbon film having excellent electromagnetic wave-shielding performance. A carbon film according to the present invention is composed of carbon nanotube aggregates, wherein the pore distribution curve, which shows the relationship between a pore diameter and a Log differential pore volume and is obtained from the adsorption isotherm of liquid nitrogen at 77K, on the basis of the Barrett-Joyner-Halenda method, has a peak at which the Log differential pore volume is maximized within the pore diameter range of 10-100 nm, and the value of the Log differential pore volume at the peak is at least 1.2 cm3/g.
