Cellulose-based composite sheet exhibits simultaneous adsorption and shielding of radioactive elements

Researchers at University of Tsukuba have developed a cellulose-based composite sheet that integrates paper pulp with starch, polyaniline (a conductive polymer), Prussian blue (a coordination compound), and alginic acid (a natural polysaccharide). These components were assembled into layered structures using a traditional papermaking technique. The resulting sheet exhibits efficient simultaneous adsorption and immobilization of radioactive elements, including cesium, iodine, and strontium.
