A MOF-based inkjet print ink of concentration 1 mg ml -1 was prepared. Briefly, 0.5 gm watersoluble MOF powder was dissolved in 50 ml DI water. Printing solvent was then added to the MOF solution. The printing solvent was prepared by adding 10 ml of propylene glycol, 10 ml of xanthan gum and 6 mg of triton x-100 into 100 ml DI water and stirring till a homogeneous printing ink was obtained. The viscosity and surface tension of the print ink were then assessed to check the ohnseroge number and the Z number to determine the printability of the MOF based ink. The printing ink was then filtered through a 0.2 µm filter to remove any impurities and large particles that could block Dimatix nozzles.
