Our standard large area (> m2) CNTSheet™ manufacturing process produces anisotropic porous carbon nanotube sheets in the 10-200μm thickness range. They have electrical and thermal properties that are uniform in the “X” and “Y” direction (sheet plane) and are 1-3 orders of magnitude lower in the “Z” direction. This manufacturing platform, using mm long VASWCNT’s or VAMWCNT’s as the primary mechanically interlocking fiber material, allows
