The wide applications of two-dimensionally ordered nanoscale features have stimulated the development of cheap and fast fabrication techniques in recent years. We achieved large area of uniform film of nanoparticles between 49.8 +/- 8.7 and 117.6 +/- 6.7 nm via flow-coating. However, the single crystalline domains of a close-packed monolayer remained limited. That motivated deposition of initially ordered colloidal dispersions, attained through deionized solutions to extend electrostatic double layers for long-range repulsion. Although the deposition agreed reasonably well with our power-law model, the initial order was destroyed at high shear. While the particle order was partially preserved during deposition at low shear, the domain size was not particularly extensive due to the high compression of double layers during evaporation.
