Sang Seok Lee, Bomi Kim, Su Kyung Kim, Jong Chan Won, Yun Ho Kim, and Shin-Hyun Kim"Robust Microfluidic Encapsulation of Cholesteric Liquid Crystals toward Photonic Ink Capsules," Advanced Materialsaccepted for publication (2014). (Co-corresponding author)


Robust photonic microcapsules are created by microfluidic encapsulation of cholesteric liquid crystals with a hydrogel membrane. The membrane encloses the cholesteric core without leakage in medium of water and the core exhibits pronounced structural colors. The photonic ink capsules which have precisely controlled bandgap position and size will provide new opportunity in colorimetric micro-thermometers and optoelectric applications.
