Abstract Scope |
The continuing demand for graphene due to its unique properties and scientific applications has driven innovation in current production technologies to speed up production. However, the production yield of graphene is still very low, which makes graphene expensive. This work focuses on the low-cost, high yield and quality graphene (HYQG) synthesized from low-cost soybean via an electrochemical exfoliation. Current methods are limited to exfoliate in flake/bulk level of graphene precursor, which cannot exfoliate HYQG. Here, a newly designed electrode is used to exfoliate particle-level graphene that achieved a yield of 70% (HYQG). This work also addresses the challenge of 3D printing of HYQG via aerosol jet printing, where controlled printing of atomized graphene-particles can create a well-controlled structure of HYQG. A parametric study for both materials and process has been conducted to optimize HYQG structures. |
