Nano-scale ZnO and In2O3-Ga2O 3-ZnO (IGZO4) suspensions for inkjet printing were prepared via a hybrid of chemical dispersion and mechanical grinding process. Anionic polyelectrolyte, poly(methacrylic acid) (PMAA), was adopted as the chemical dispersant and the optimum condition was established by studying the dispersion behaviors of ZnO suspensions. It was found that, by adding 3 wt.% of PMAA-Na, the lowest viscosity, smallest sediment volume and particle size (d50) could be achieved in ZnO suspensions. The same hybrid process was then applied to prepare the nano-IGZO4 suspensions and at present the particles with the average particle sizes about 53 nm could be obtained.
