Abstract
Elastic conductors made of ribbons of aligned carbon nanotubes embedded in a matrix of poly(dimethylsiloxane) exhibit a stabilized resistance after several cycles of stretching and releasing. The elastic conductors were prepared by drawing a ribbon of carbon nanotubes from an aligned array of carbon nanotubes and positioning on cured poly(dimethylsiloxane). After providing each end of the ribbon with an electrode, a film of uncured poly(dimethylsiloxane) was cast on the ribbon and electrodes. After curing the film an elastic conductor was produced. The electrical resistance of this elastic conductor became stable after a few cycles of stretching and releasing to strains up to 100%.

3. A method for preparing an elastic conductor, comprising:
-
drawing a ribbon of aligned carbon nanotubes from a supported array of aligned carbon nanotubes, positioning the ribbon of carbon nanotubes on cured poly(dimethylsiloxane), the ribbon having a first end and a second end, forming a first electrode at the first end of the ribbon, forming a second electrode at the second end of the ribbon, casting a film of uncured poly(dimethylsiloxane) on the ribbon and cured poly(dimethylsiloxane) whereby alignment of the carbon nanotubes is maintained, and curing the film. - View Dependent Claims (4, 5)
