Abstract
An electrically conducting talc composition may include synthetic talc particulate coated with an electrically conducting coating agent, wherein the coating agent may include carbon nanotubes or an electrically conductive polymeric material, such as a nanocarbon material, such as, for example, carbon nanotubes. A method of making an electrically conducting talc composition may include forming electrically conducting coating agent on or about particles of the talc particle.

1-20. (canceled)
An electrically conducting talc composition comprising synthetic talc particulate coated with an electrically conducting coating agent.
An electrically conducting talc composition comprising natural talc particulate coated with an electrically conductive polymeric material, such that if the talc composition comprises no particulate other than natural talc particulate, the talc composition further comprises a connecting chemical linker between a surface of the natural talc particles and at least a portion of the electrically conducting polymeric material.
A method of making an electrically conducting talc composition comprising natural talc particulate coated with an electrically conductive polymeric material, the electrically conducting talc composition comprising a connecting chemical linker between a surface of the natural talc particles and at least a portion of the electrically conducting polymeric material, the method comprising:
- combining a chemical linker moiety and natural talc particles under suitable conditions to produce natural talc particulate comprising talc particles having chemical linker moieties attached thereto;
- and
- forming an electrically conducting polymer material on or about particles of the talc particulate,
- wherein at a least a portion of the electrically conducting polymeric material is connected to the talc particles via the chemical linker moiety.
