Synthesis, Mechanical Characteristic and Near-infrared Reflective Property of Perylene Diimide-containing Polyurethane

On March 20, 2025, a team of experts led by SONG Yi-fan, TIAN Kai-li, REN Xiang-kui from the School of School of Chemical Engineering and Technology published an article in the 发光学报, introducing its research progress in the field of near-infrared reflective materials. The team synthesized a novel polymer PU-PDI with intrinsic NIR reflective properties by covalent incorporation of PDI units into polyurethane chains, which provides solutions to solve the problems of mechanical properties and NIR reflectance properties compromised due to macro-phase separation.
