Preparation of Polymer Fluorescent Element by Radiation-Induced Graft Polymerization and Polymer Fluorescent Element

摘要

PURPOSE: A process of preparing a polymer phosphor by irradiating radioactive rays (electron beam or gamma ray) to polymer material to introduce a vinyl based monomer and bonding a rare earth ion to the functional group of the vinyl based monomer is provided, which can produce a phosphor at low cost in a simple manner at ordinary temperature. The process also has the advantage of having no complicated manufacturing and inspection processes and installing conveniently. CONSTITUTION: The process for the production of a polymer phosphor comprises the steps of generating radicals by irradiating radioactive rays to a vinyl based monomer having a functional group; introducing acrylic acid having carbonic acid by reacting a mixture solvent of water/methanol to a reaction sample at 30 to 70deg.C; dipping the washed grafted polymer in a caustic soda solution at ordinary temperature for 1 to 5 hr to substitute sodium for a carboxyl group and settling in a rare earth element aqueous solution when the reaction is completed; and washing with distilled water and drying.
