Prof. Shinhyun Kim aims to recognize the limits of the standardized pattern production technology with a single structural color in the age of technological sensibility and realize a structural color for 2D/3D printing and colloidal self-array through the direct writing of the photopolymerizable colloid ink that can overcome this limit.

This study aims to put to practical use a structural pigment that expresses various colors and colors that chemical pigments cannot realize by imitating natural structural colors, has no fading and discoloration and has high thermal stability and low toxicity. Through this, if susceptible structural colors are 2D patterned and 3D structured, it is possible to manufacture customized products that maximize the individuality of consumers, leading to the technology of susceptible optical materials. In addition, aesthetic, structural color patterning is possible without coloring in various fields such as clothing, contact lenses, and smartphones.

Direct writing-based structural color patterning research is a new field yet to be reported. Therefore, the research results will present a new paradigm for research on the development of susceptible optical materials and will significantly help secure original technology for developing practical structural color materials.
