A technology for creating images based on changes in nanostructures has been developed

A revolutionary technology has been developed that allows you to obtain images in real time using changes in nanostructures. This innovative technology, developed by Professor Kang Hee Koo and her team from UNIST’s School of Energy and Chemical Engineering, has the potential to revolutionize various fields, such as the creation of smart polymer particles.

Using block copolymers, the research team achieved self-assembly of photonic crystal structures on a large scale, mimicking the natural phenomena observed in butterfly wings and bird feathers. By mapping the shape and direction of nanostructures, this technology allows for vivid colors to be visualized in real time.

Block copolymers, consisting of two or more different monomers covalently linked in the form of a block, have been used to separate phases in immiscible liquid droplets. Professor Ku emphasized the significance of this achievement, stating: “We have successfully created hundreds of flawless photonic crystal structures through the autonomous organization of block copolymers, eliminating the need for external manipulation.”

The key innovation is the use of a polymer that can dynamically change the size of the microstructures inside the particles in response to changes in the external environment. Using the unique properties of polystyrene-polyvinylpyridine (PS-b-P2VP) block copolymers, it is possible to adjust the structure, shape and color of the particles, returning them to their original state despite changes in the environment.

Professor Ku expressed her confidence in the potential applications of this research, stating: “This research opens the door to the creation of self-assembled optical particles by simplifying the complex process conditions usually associated with colloidal crystal structure and patterning.” She further noted: “Practical applications of the technology are possible in smart paints and polymer particles in various industries.”
