Resumen de: US2020407571A1

The present disclosure provides advantageous sheet stabilized emulsion based inks, and improved methods for fabricating and using such inks. More particularly, the present disclosure provides improved methods for fabricating conductive inks derived from water-in-oil emulsions stabilized by sheets exfoliated from layered materials (e.g., substantially pristine and non-oxidized graphite or hexagonal boron nitride), and related methods of use. A layered material (e.g., substantially pristine and non-oxidized graphite or hexagonal boron nitride) can be exfoliated into individual sheets, and these sheets can be utilized to stabilize water-in-oil emulsions. In certain embodiments, by utilizing long chain alkanes (e.g., hexadecane), one can advantageously fabricate emulsions with high viscosity and stability. In this form, the emulsions can be used as inks, thereby advantageously providing an inexpensive route to printing electrically conducting and/or insulating lines and shapes.
