Carbon nanopaper (CNP) exhibits qualities that are desirable for a number of applications such as flame retardancy, lightning protection, and flexible printed circuit boards. CNP has become a desired engineering material in many important sectors of industries such as space, automotive, aviation, and military.

CNP has become a desired engineering material in many important sectors of industries such as space, automotive, aviation, and military. However the production of consistent thicknesses and dispersion remains a challenge for practical use. Most of the standard methods of production do not allow for continuous applications or digital fabrication of the CNP. In this work, CNP is produced two different ways that allows for continuous production and digital fabrication. The continuous CNP making technique uses vacuum infiltration along with air atomization and a continuous drive belt system to produce a continuous roll of the CNP. This system is able to produce an 11 (&)#181;m (&)#177; 2 (&)#181;m CNP at 6 inches per min with an electrical resistivity of 59 ? per square. The major advantage of this production process is the ability to mass manufacture the CNP. Spray deposition modeling (SDM) is a digital fabrication process that uses a 12 array bubble jet nozzle attached to a digital control x-y plotter combined with a heated substrate which induces evaporation. This process is able to produce paper with variable thicknesses in defined locations. The maximum thickness of the CNP produced is 10 (&)#181;m with a resistivity of 95.7 ? per square. A strong advantage of this CNP production method comes from the ability to digitally print images. The controllable thickness and selective location printing presents an effective alternative to costlier methods and provides a solution to many geometrical CNP issues.
