The method comprises forming a mixture including carbon nanotubes, a polymeric compound, surfactant and water; introducing the mixture to a substrate; and evaporating water from the mixture to form a composite film on the substrate.
Claims26
A method for fabricating an electrically conductive composite structure, comprising:
- forming a mixture including carbon nanotubes, a polymeric compound, surfactant and water;
- introducing the mixture to a substrate;
- and
- evaporating water from the mixture to form a composite film on the substrate.
A method for fabricating an electrically conductive composite structure, comprising:
- forming a first solution including multi-walled carbon nanotubes, surfactant and water;
- forming a second solution including water and a polymeric compound selected from at least one of water soluble polymer-like polyethylene oxide and polyvinyl alcohol;
- mixing the first and second solutions together to form a third solution;
- introducing the third solution to a substrate;
- and
- subjecting the third solution to an evaporation casting procedure, the evaporation casting procedure causing a composite film to remain on the substrate after the water evaporates from the third solution.
An electrically conductive composite film for use as a strain sensor formed by subjecting a substrate to an evaporation casting procedure, the substrate being immersed in a mixture during the evaporation casting procedure, wherein the mixture comprises carbon nanotubes, a polymeric compound, surfactant and water.
