Abstract
A polymer-carbon nanotube composite film is provided for use as a sensor for detecting chemical vapors. The composite film is formed by coating perpendicularly-aligned carbon nanotubes with a polymer selected from poly(vinyl acetate), poly(isoprene), or blends thereof. The sensor may be formed by attaching at least two electrodes to the polymer-carbon nanotube composite film. The sensor may be used in any applications where the sensor is capable of detecting a change in conductivity in the composite.
Claims7
A method of making a sensor comprising:
- forming aligned carbon nanotubes on the surface of a substrate;
- wherein said nanotubes are aligned perpendicularly with respect to said substrate;
- partially coating said aligned carbon nanotubes from the top down along their length with a polymer to form a composite film;
- removing said composite film from said substrate;
- and
- attaching at least two electrodes to said film.
