Methods, systems, and devices are described to fabricate precursor intermediaries and carbon fiber or graphene materials. In one aspect, a method to fabricate an acryl-modified polymer includes obtaining a hydrocarbon substance from one or both of a waste stream or natural gas, separating gases from the hydrocarbon substance to form hydrogen gas and a carbonaceous gas including one or more of methane, butane, or ethane, dehydrogenating the carbonaceous gas by adding heat to form a dehydrogenated carbon material, and reacting the dehydrogenated carbon material with a nitrogen material including one of ammonia or urea to produce polyacrylonitrile (PAN).

1. A method to fabricate carbon fibers or graphene, comprising the steps of: obtaining a precursor material from a hydrocarbon substance from one or both of a waste stream or a fossil fuel source, wherein obtaining the precursor material comprises: separating gases from the hydrocarbon substance to form hydrogen gas and a carbonaceous gas;dehydrogenating the separated carbonaceous gas by adding heat to form a dehydrogenated carbon material; andreacting the dehydrogenated carbon material with a nitrogenous material to produce the precursor material,processing the precursor material to produce carbon fibers,wherein processing the precursor material causes nitrogen and hydrogen to be released. 2. The method as in claim 1, wherein the produced carbon fibers include a fuzzy fiber structure, a twisted fiber or a flat fiber structure. 3. The method as in claim 1, wherein processing the precursor material includes forming an internal nanofiber or a microfiber within the produced carbon fibers. 4. The method as in claim 3, further comprising: forming adhesive bonds to the internal nanofiber or microfiber by chemically or radiatively cross-linking. 5. The method as in claim 1, wherein the separated carbonaceous gas includes one or more of methane, ethane, propane, or butane. 6. The method as in claim 1, wherein the nitrogenous material includes one of activated nitrogen, ammonia, or urea. 7. The method as in claim 1, wherein the produced precursor includes polyacrylonitrile (PAN). 8. The method as in claim 1, wherein the produced precursor includes a polyolefin. 9. The method as in claim 1, wherein the produced precursor includes one or more of polyethylene, polypropylene, or polybutylene. 10. The method as in claim 1, wherein the reacting further produces other nitrile substances or paraffinic substances. 11. The method as in claim 1, wherein the adding the heat includes applying the carbonaceous gas across an array of heat sources in a controlled atmosphere by a vacuum furnace. 12. A method to produce a fuzzy carbon fiber composition comprising the steps of: forming a precursor into a tensioned fiber;dehydrogenating the tensioned fiber to produce a carbon graphite fiber;developing architectural constructs on the tensioned carbon fiber to produce a fuzzy fiber composition. 13. The method as in claim 12 wherein the step of developing includes depositing architectural constructs on the tensioned carbon fiber. 14. The method as in claim 12 wherein the step of developing includes forming architectural constructs on the tensioned carbon fiber. 15. The method as in claim 12 wherein, the architectural constructs include one or more of silicon carbide, silicon nitride, boron nitride, single walled carbon nanotubes and multi walled carbon nanotubes. 16. The method as in claim 12, wherein the forming step comprises at least one of spinning, pulling, and drawing the precursor. 17. The method as in claim 13 wherein, the step of depositing architectural constructs comprises of adding iron to a carbon solution to initiate and produce the architectural construct.
