High Strength Carbon Nanofibers with Modulated Surfaces

 

Carbon fiber technology is predominantly focused on microfibers in the range of X to Yum. Such fibers have been optimized heavily over the past decades and are now used ubiquitously. Carbon nanofibers on the other hand are a new idea and are currently fairly crude, relatively short, unaligned, relatively impure, and necessarily smooth thereby limiting possible applications. The possibilities for carbon nanofibers are very diverse as they have the potential to be used in any conventional microfiber application but can be used in smaller laminar applications with dramatically improved results. This technology is a method and composition of matter used for creating carbon nanofibers that are continuous, aligned, near-zero impurity, and high-strength.

Details

This technology is a proprietary method of inexpensively, easily and reproducibly creating high mechanical property carbon nanofibers.

Applications

This carbon nanofibers technology has very significant applications. Because these nanofibers have comparable mechanical properties to carbon microfibers, they can be used analogously in any application a carbon microfiber can be used (for which the global market is many billions). However, these nanofibers have applications that microfibers cannot fulfill, such as ultra-thin laminar layers in high performance composites.

Benefits

These carbon nanofibers have dramatically improved properties when compared to any other carbon nanofibers currently available on the market.

  • Size: there are currently no carbon nanofibers on the market that have performance near this technology. Current market offerings have strength orders of magnitude lower than these nanofibers. Additionally, currently available fibers cannot be aligned, which dramatically decreases the number of potential applications.
  • Strength and Durability: the tensile strength of these optimized fibers is nearly an order of magnitude higher than what is currently produces and is nearly equal to the industry standard Toray fibers while being significantly smaller. The adhesive strength of these fibers in polymeric materials can be selectively modulated to be dramatically increased by using a proprietary method of creating a uniformly rippled fiber surface.
  • Alignment: this fabrication technique and material choice allows the nanofibers to be formed in a highly aligned manner as opposed to the current birds nest tangle current manufacturing methods necessitate. Such alignment allows much broader application of these fibers.
  • Surface Modulation: a unique process has been developed to allow even, reproducible and tunable surface modulation or rippling. Such rippling allows much better adhesion in polymeric substrates for a dramatically stronger composite.
