Abstract:
The present invention relates to an ink formulation comprising two-dimensional inorganic layered particles. The ink formulations of the present invention are for inkjet printing. The present invention also relates to a process for the preparation of these ink formulations, to the use of these ink formulations for the production of printed films and tracks comprising the inorganic material, to the films or tracks produced by the inkjet printing of these ink formulations, to devices that comprise these films or tracks, and to systems comprising an array of these devices.

Claim (Index 30):
A process for the preparation of the ink formulation of  claim 1 , the process comprising:\n a) providing a source of an inorganic material in a first aqueous medium comprising a stabilizer; b) subjecting the source of the inorganic material in the first aqueous medium of a) to energy to break up or exfoliate the source of the inorganic material, thereby to obtain an aqueous dispersion of nanosheets of the inorganic material in the first aqueous medium; c) if the aqueous dispersion of nanosheets obtained in step b) above comprises residual source inorganic material that has not been converted into dispersed nanosheets, separating said residual source inorganic material from the aqueous dispersion; d) separating the dispersed nanosheets from the first aqueous medium following step b) or step c) and then redispersing the nanosheets in a second aqueous medium; e) separating the dispersed nanosheets from the second aqueous medium following step d) then redispersing the nanosheets in a further aqueous medium one or more times; f) separating the nanosheets from the further aqueous medium subsequent to step (e) to obtain collected nanosheets; and g) re-dispersing the collected nanosheets of step (f) in an aqueous vehicle comprising at least one surface tension modifier and at least one viscosity modifier, thereby to form the ink formulation.
