Abstract
A high‐Z metal‐quercetin complex‐based material is developed by combining Hf, Ta, and Eu with quercetin (Qu) from a flavonoid series to apply to radiation protection materials. To demonstrate radiation energy absorbance, we utilize a polymer blend composed of carboxymethyl cellulose (CMC) and polyvinylpyrrolidone (PVP) as a matrix. This eco‐friendly film can be easily prepared by simply mixing it with the M‐Qu complex and the CMC‐PVP polymer blend. The possibility of radiation energy absorbance by the M‐Qu complex is confirmed through an analysis of the X‐ray energy absorption dose change rate. In addition, the radiation resistance characteristics of each film sample are measured using high‐energy electron‐beam irradiation. The results show that the Ta‐containing Qu complex has a high capability for UV energy downshift, X‐ray radiation absorption, and stability against electron‐beam radiation. This indicates that the material in question has the potential to serve as a superior radiation protection material for broad‐spectrum radiation energy. Also, it could effectively offer remarkable stability making it a compelling option for radiation‐resistant applications.
