  • Polyester nanocomposites for protection from hazardous radiation used for medical applications
    Patent number: 11217354
    Abstract: A radiation shielding material is fabricated by providing a mixture of a polyester polymer and lead oxide. The material can be formed by the open mold cast technique. A nanocomposite material comprising at least 10% lead oxide is used to provide shielding for diagnostic or medium x-rays. A formulation comprising 40% of lead oxide nanofiller embedded in a polyester matrix performed best at attenuation of diagnostic and medium x-ray levels.
