Summary:
Iowa State University researchers have demonstrated the ability to create anisotropic buckypaper by filtration of a water-borne carbon nanotube solution in a shear field;  the shear forces cause the carbon nanotubes to align along the direction of fluid flow.

Development Stage:
 
Description:
Alignment of carbon nanotubes (CNT) has long been known to provide exceptional stain, electrical and other properties.  Unfortunately, traditional methods utilizing electric fields, magnetic fields and mechanical stretching are costly and difficult to scale to production volumes.

Advantage:
• Moderate shear rate provides high degree of anisotropy
• Low cost, scalable procedure
Application:
Carbon composite materials
