Abstract
An electrically conductive composite comprising a polyvinylidene fluoride polymer or copolymer and carbon nanotubes is provided. Preferably, carbon nanotubes may be present in the range of about 0.5-20% by weight of the composite. The composites are prepared by dissolving the polymer in a first solvent to form a polymer solution and then adding the carbon nanotubes into the solution. The solution is mixed using an energy source such as a sonicator or a Waring blender. A precipitating component is added to precipitate out a composite comprising the polymer and the nanotubes. The composite is isolated by filtering the solution and drying the composite.
Claims15
A polymer composite comprising:
- a compound comprising a mixture of at least two substances selected from the group consisting of polyvinylidene fluoride, copolymer of vinylidene fluoride and another monomer, and another polymer;
- and
- carbon nanotubes in an amount from about 0.01 to 30% by weight of said composite, wherein said nanotubes have a diameter less than about 100 nanometers.
