Physicists roll out nanotube paper

Abstract:
Rolling a small steel cylinder across an array of carbon nanotubes (CNTs) is a quick and easy way of preparing "buckypaper"a thin material that is an excellent conductor of both heat and electricity. Invented by physicists at Tsinghua University, China, the new technique could be used to make materials that boost the performance of high energy density supercapacitors or remove heat from computer chips.

The team's production method really is as simple as it sounds. They begin with arrays of millions of CNTs that have been grown on a silicon substrate using a well-established technique. The arrays, which resemble a forest with all the CNTs aligned perpendicular to the silicon surface, are about 10 cm in diameter and the CNTs are about 100 m tall.
