China is one of those countries which suffer from the problem of serious ice covering on transmission lines and the ice damage most heavily in the world. It has become an important and urgent task to develop ice-resistant technology and reliable ice protection technology and adopt targeted preventive measures and treatment methods. It will bring great value to improve the safe operation of power system and will have remarkable market prospect.
The present research combines the advantages of graphene and additivemanufacturing (AM) by integrating graphene in a micro-scale aerosol-jetAM process. To print graphene patterns, a high-concentration graphene-based ink, compatible with the AM system, was developed using a chemical exfoliation process. This ink, with a graphene concentration of 3.1 mg/mL and a viscosity of 20 cP, comprises graphene flakes with lateraldimensions below 30 nm, ethyl cellulose as a stabilizer for grapheneflakes, and a mixture of solvents that are compatible with the printingprocess. Subsequently, the graphene patterns with resistivity as low as0.018 Ω.cm and widths ranging from 10 to 90 microns was successfullyperformed. These patterns, which are the finest ever printed graphenepatterns, may develop miniaturized printed electronic applications ofgraphene.
