Polymeric Responsive Intelligent Structural Materials

We optically fabricate precise 3D micro-structures and apply them to tactile sensor systems and to the production of 3D full-parallax hologram patterns. Our lab’s research spans the synthesis of functional conjugated polymers; organic-inorganic hybrid materials; soft lithography for microfluidic channel fabrication; 3D/4D printing; 3D holography; and structural-color systems. In addition, we design and synthesize stimuli-responsive organic materials and conjugated polymers that undergo distinct color changes upon external cues(e.g., pH, mechanical strain, humidity, volatile organic compounds, and toxic gases) to enable rapid and accurate detection of nerve agents, advancing chemical, biological, radiological, and nuclear (CBRN) sensor technologies. Building on these capabilities, we develop anti-counterfeiting systems by designing and synthesizing functional organic-inorganic unanomaterials with tailored optical properties and by continuously manufacturing microstructures with nprecedented optical responses using three-dimensional microfluidic channels.
