Abstract
A composite fiber having a core sheath-structure that includes a core portion having an electrically conductive material, and a sheath portion having a ceramic component covering the core portion. The composite fiber is constructed such that, when the core portion is connected to a ground, the sheath portion exhibits one of a positive surface potential or a negative surface potential over an entire surface of the sheath portion.
Claims18
A composite fiber comprising:
- a core portion comprising an electrically conductive material;
- and
- a sheath portion comprising at least one ceramic component selected from aluminum oxide, zirconium oxide, tricalcium phosphate, and apatite covering the core portion,
- wherein, when the core portion is connected to a ground, the composite fiber is constructed such that the sheath portion exhibits one of a positive surface potential or a negative surface potential over an entire surface of the sheath portion.
