Electrically conductive material, emitter containing electrically conductive material, and method for its manufacture

A method for manufacture of an electrically conductive material, the method comprising the steps of:

• a) providing a structure made of electrically conductive fibers;
• and
• b) producing a carbon-based, electrically conductive matrix that at least partially envelopes the electrically conductive fibers;
• wherein, before or after producing the matrix, at least part of the electrically conductive fibers are interrupted in a direction of possible current flow.

An electrically conductive material comprising:

• a) a structure made of electrically conductive fibers;
• and
• b) an electrically conductive matrix which at least partially envelopes the electrically conductive fibers;
• wherein the electrically conductive fibers exhibit higher specific conductivity than the electrically conductive matrix;
• wherein the electrically conductive material extends in a direction of longitudinal extension;
• and wherein, viewed along the direction of longitudinal extension, at least part of the electrically conductive fibers within the material are interrupted at least once.
