Problems solved by technology

Although graphitic intercalation compounds have desirable electrical conductivity and reduced weight when compared to similarly sized metallic electrical conductors, graphitic intercalation compounds are generally brittle and susceptible to exfoliation of graphite layers when exposed to increased temperatures Impact
Furthermore, intercalation of graphitic carbon with guest molecules or atoms generally only increases the in-plane conductivity of graphitic carbon and decreases the conductivity of graphitic carbon normal to that plane.

Embodiment Construction

[0018] Implementations described herein relate to electrical conductors formed at least in part from graphitic intercalation compounds (GICs). GICs are formed from carbon-based particles with multiple guest molecules inserted into them. In an exemplary implementation, the GIC is then surrounded by a conductive material to form an electrical conductor as described herein. For example, the conductive material may be in the form of at least one layer of conductive material or an underlying matrix of conductive material. A GIC can have about five times higher in-plane conductivity and about four times less weight than a similarly sized metallic electrical conductor, such as copper. Accordingly, the electrical conductors described herein are lighter in weight and have at least comparable electrical conductivity than similarly sized electrical conductors formed from known metallic conductive materials.

Abstract

An electrical conductor is provided. The electrical conductor includes a graphite intercalation compound and at least one layer of electrically conductive material extending over at least a portion of the graphite intercalation compound. The graphite intercalation compound includes a carbon-based particle and a plurality of guest molecules intercalated in the carbon-based particle.

Description

technical field [0001] The field of the present disclosure relates generally to electrical conductors, and more particularly to electrical conductors formed at least in part of graphitic intercalation compounds. Background technique [0002] In at least some known applications, power, current and electrical / electronic signals are often conducted through wires or cables. In general, known wires or cables comprise a conductor core and an insulating sheath peripherally arranged around the conductor core. At least some known wire cores are fabricated from materials such as copper, silver, gold and aluminum. While these known materials have desirable electrical conductivity, weight reduction is an ongoing goal in many applications by developing electrical conductors with reduced weight and electrical conductivities at least comparable to known metallic electrical conductors. For example, in the aerospace industry, reducing the weight of an aircraft often results in increased fu...
