Colloidal particles have been widely employed in materials science as templates for creating functional materials, model systems for investigating intrinsic forces in self-assembly, and phase transition behaviors of materials. Electrolytic oxidation of colloidal nanoparticles easily takes place during electrophoretic movement due to the flow of electrons between electrodes for electrochemical electrolysis of dispersion, usually water molecule. To extend their application using aqueous solution, the only theoretical way to get a small current flow through the water which degrades entire system is capacitor system. We designed such system and observed that photonic aqueous solution in thin-layer double emulsion microcapsules made by the microfluidic chip is electrically stable at high electric field. In addition, we would control the shell thickness of capsules for active tuning of self-assembly and observed reflection wavelength to confirm crystal forming. These properties could be a good stepping stone for developing practical applications of photonic displays. |
