The present invention describes a method of creating lightweight efficient parabolic solar panels and a unique approach to realize improved alignment of nanotubes in buckypaper materials.

This invention provides a new method to align carbon nanotubes in buckypapers by stretching thermoplastics/buckypaper films. Buckypaper is a thin film (approximately 20µm) of nanotube networks, which can be utilized in various products, such as composites, electronic devices and sensors. Since nanotubes are highly anisotropic in nature, the alignment of nanotubes in buckypaper is critical for achieving high mechanical performance and high electrical and thermal conductivity.


  • This invention has an excellent potential for use in the mass production of high-performance nanotube and nanofiber-reinforced epoxy composites
  • The significantly improved alignment is key factor toward realizing the potential of nanotubes for high mechanical, electrical and thermally conductive applications in composites and electronic devices
  • The high-performance buckypaper nanocomposites can be used for EMI shielding, thermal management and structural materials applications
  • Immediate applications include composite applications for aircraft and thermal management for electronic device package. High-performance buckypaper materials are also expected to be widely used to develop lightweight-conducting films and current-carrying materials for electronic products
