Abstract
Provided herein are composite conductors, characterized by having copper deposits inside the bulk rather than on the outer surface of a non-metallic conductive porous matrix, such as CNT fabric, as well as a process for obtaining the same. The composite conductors provided herein are also characterized by a low specific weight and a high ampacity compared to metal conductors of similar size and shape.
Claims16
A composite conductor element, comprising a non-metallic conductive porous matrix and a plurality of metallic copper particles incorporated therein, wherein:
- said non-metallic conductive porous matrix is a randomly oriented matrix;
- said copper particles are incorporated within a bulk of said non-metallic conductive porous matrix, and
- said copper particles are arranged in clusters of metallic copper crystals having a size that ranges from 1 nm to 150 μm, and being connected to each other by metallic copper threads forming a metallic copper network on and within said bulk of said non-metallic conductive porous matrix;
- the composite conductor element is characterized by an ampacity of at least 100 A/cm2 over at least 100 μm of the element, and is scalable and capable of forming macroscopic conductive elements.
