Abstract
An industrial process is conducted within a sealed chamber filled with dimethylformamide (DMF) saturated with CO2 under pressure which provides the carbon atoms for manufacturing graphene. A copper wire comprising an anode is reeled between two spaced reels on opposite sides of the sealed chamber, preferably above and below a container within the chamber. Electrical voltage is supplied to a graphite and Galinstan-Cerium electrode which acts as a cathode and during the process a chemical reaction is induced between the Galinstan-Cerium electrode and the CO2 saturated DMF liquid so that graphene is deposited on the copper wire which acts as an anode.

An apparatus for depositing graphene onto an electrically conductive wire, comprising:
- a) a sealed chamber containing pressurized CO2 gas saturated Dimethylformamide (DMF);
- b) a container within said chamber having a top comprising a cathode and said container having upper and lower openings;
- c) said cathode including a first portion made of material composed of an alloy that is liquid at room temperature and comprises a mixture of 68-69% by weight gallium, 21-22% by weight indium and 9.5-10.5% by weight Tin, said alloy mixed with Cerium to serve as an electrode, and a second portion made of graphite and surrounding said first portion;
- d) a wire comprising an anode and conveyable through said container into said upper opening and through said lower opening;
- e) a source of electrical power connected to said cathode and, when activated, conveying electrical current through said cathode;
- f) a gap between said cathode and said wire;
- g) whereby, with said source of electrical power activated, as said wire is conveyed into said upper opening and through said lower opening through said container, a chemical reaction between said cathode and said DMF and CO2 causes graphene to be deposited onto an outer surface of said wire.
