Problems solved by technology

However, the morphology of these nanoparticles is basically spherical or ellipsoidal. Even after sufficient ultrasonic dispersion, there is still a serious agglomeration phenomenon between the particles, and it is not easy to disperse in organic solvents.
However, inkjet printing equipment is different from spin coating, printing and other luminous layer preparation processes, and its requirements for ink are relatively high, such as suitable boiling point, viscosity, surface tension and uniform and stable dispersion. Therefore, bismuth titanate series compounds should be used Applied to inkjet printing inks, there are still some difficulties
