    摘要: The present disclosure is directed to providing a carbon film having an excellent shield performance against electromagnetic waves. The carbon film of the present disclosure is a carbon film made of a carbon nanotube assembly, wherein a pore distribution curve of the carbon film indicating the relationship between the pore size and the Log differential pore capacity obtained from an adsorption isotherm at 77 K of liquid nitrogen based on the Barrett-Joyner-Halenda method has a peak in which the Log differential pore capacity is maximized within a pore size range of 10 nm or more and 100 nm or less, and the value of the Log differential pore capacity at the peak is 1.2 cm3/g or more.

    摘要: A nanofiber forest is described that has been processed to increase a number of nanofibers per unit area (referred to as “areal density” or, equivalently, “density”) compared to the nanofiber forest in its as-synthesized state. This increase in areal density is accomplished by physically manipulating a deformable substrate on which the nanofiber forest is disposed. At a high level, this physical manipulation begins by transferring the nanofiber forest from a growth substrate to a deformable substrate. A surface area of the deformable substrate is reduced relative to a surface area of the substrate when the nanofiber forest was attached. This reduction in area causes the nanofibers in the forest to move closer to one another, thus increasing the number of nanofibers per unit area.
