摘要

We develop a chemical formulation to synthesize stable IrO2 colloidal solution as a bio-ink for ink-jet printing purpose. This wet chemical process entails Na3IrCl6 and NaClO as the Ir precursor and oxidizer, respectively. In addition, citric acid and sodium hydroxide are employed as the complex agent and pH adjuster. The pH value of the IrO2 colloidal solution could be readily adjusted over a broad range without incurring undesirable precipitation. Their respective zeta potential decreases from positive to negative with increasing pH values. The IrO2 colloidal solution demonstrates impressive chemical stability over extended storage at 5 and 65 degrees C. Images from transmission electron microscope indicate the average size for the IrO2 nanoparticles to be 3.5 nm. The X-ray diffraction pattern from the heat-treated IrO2 sample shows a polycrystalline rutile phase. The IrO2 colloidal solution undergoes repeated filtering and washing to retrieve the IrO2 nanoparticles. After an annealing at 450 degrees C for 2 h in air, the crystalline IrO2 nanoparticles are resuspended in a 0.5 wt% aqueous medium as the bio-ink for ink-jet printing on an ITO substrate. Our method enables the synthesis of stable IrO2 nanoparticles in a neutral solution at 25 degrees C, which provides a facile and effective approach over conventional ones that require alkaline environment at elevated temperature.
