Inorganic Specialists Inc., produces flexible papers made of multi-walled carbon nanofibers (MWCNF).  Nanofibers are 10-150 nm diameter multi-walled carbon nanotubes (MWCNT or MWNT).   They are called nanofibers to distinguish them from single-walled nanotubes (SWNT) which are less than 10 nm diameter and exhibit quantum effects.

 

This thin, porous, flexible form of multi-wall nanotubes is a practical and user-friendly substrate, known to have uses in composites and EMI shielding, energy damping, fuel cell catalyst host, electrochemical capacitors, and energy storage such as rechargeable Lithium-ion battery anodes.

Nanofiber Paper—2 varieties, plus custom options.

Standard nanofiber paper is 9-10 mils thick, with a density of  approximately 0.3 g/cc,  compressible to a density of 1g/cc.   It is 80%porous, flexible, and thoroughly wetted by water, alcohol, or epoxy resin.    The standard paper is made of pure nanofibers with no polymeric binder.    Its surface area is  ~100 m²/g.

Custom Options  — Thinner or thicker sheets, binders, or custom compositions.   Details at Ordering.

High Surface Area nanofiber paper is ~7 mils thick, with a density of approximately 0.5 g/cc.   It contains a higher percentage of smaller diameter nanofibers, increasing the paper’s  surface area to 300 m²/g.
