Ecolor: Synthesis of EInk Microcapsules for Fabricating DIY Displays
summary
A reproducible, lower‑hazard method produces EInk microcapsules by adapting microencapsulation "mayonnaise" method with surface modification of titanium dioxide 30–100 nm particles, yielding capsules averaging ~50 µm (max <200 µm). Prototypes include hand‑drawn patterns and a 3×3 pixel array that switch color in ~0.5 s using ITO electrodes and a violet dye as the dark phase, shells crosslinked for ~3 month shelf life, and six novice participants report 83% find the procedure easy.
