With their superior
mechanical
properties, structural uses for carbon nanotubes have been proposed
in everything from cloths, sports equipment, and light bulb filaments
to combat armor, suspension bridges and synthetic muscles.
Sheets of cellulose infused with aligned nanotubes, thin as a sheet of paper, act as paper batteries. The tubes act as electrodes, allowing it to conduct electricity. It can function both as a battery, providing a long steady power output, or a super-capacitor, providing a quick burst of high energy. The paper battery combines all the components of a standard battery into one structure, increasing efficiency.
With their high thermal conductivity and low weight, a cooling device 1 millimeter thick has comparable cooling properties to a copper one of 20 times the weight.
