We investigate the photochemical reactions and photodegradation mechanisms of functional polymers using advanced electron spin resonance (ESR) spectroscopy. Radical intermediates generated during photoinduced reactions are identified by direct ESR measurements and spin-trapping techniques, enabling us to elucidate reaction pathways and degradation mechanisms. ESR spectral simulations are further employed to support the interpretation of radical species and reaction processes.

Our research focuses on functional polymeric holographic materials for advanced photonic applications. We investigate photorefractive polymers and photochromic materials to develop rewritable optical recording media, holographic displays, optical memory, and smart photonic devices. By combining molecular design, material synthesis, and device fabrication, we aim to achieve high diffraction efficiency, fast response, excellent optical stability, and reversible light-induced functionality. Our recent studies have demonstrated high-performance polymer composites with enhanced holographic recording capability and visible-light-responsive photochromic films exhibiting remarkable optical switching behavior.

Our research focuses on the development of flexible fibrous dosimeters by integrating photochromic dyes, photopolymerization, and centrifugal spinning technologies. Photochromic dyes embedded in polymer nanofibers undergo visible color changes upon exposure to ionizing radiation, enabling rapid and intuitive dose visualization without electronic devices. By combining photopolymerizable polymer systems with centrifugal spinning, we fabricate lightweight, highly porous nanofiber membranes with excellent sensitivity, mechanical flexibility, and large surface areas. These fibrous dosimeters have great potential for applications in medical radiation therapy, radiation safety management, environmental monitoring, and wearable radiation sensing.
