Films of aligned carbon nanotubes are apparently super-compressible and could be used to create nanotube foams that maintain their resilience even after thousands of compression cycles. In conventional foams, strength and flexibility are mutually exclusive. With the carbon nanotube foam, there is no such tradeoff. These nanotubes can be squeezed to less than 15% of their normal lengths and might be useful in flexible electromechanical systems or energy-absorbent coatings.
