Tsukuba, Japan—By incorporating functional polymers into cellulose fibers or through chemical modification of cellulose at the molecular level, composite materials with a wide range of practical applications can be produced, such as oil-resistant food packaging, filtration media, and electromagnetic shielding sheets. In this study, four cellulose-based composites were prepared by combining paper pulp individually with starch, polyaniline, Prussian blue, and alginic acid. These composites were subsequently stacked and processed into a single integrated sheet using conventional papermaking methods, enabling uniform integration of cellulose and functional polymers. The resulting composite demonstrates the ability to adsorb and block hazardous radioactive species, including cesium, iodine, and strontium, in a single step, highlighting its potential for environmental contamination control.
