摘要：
A novel transparent polymer neutron scintillation material poly[styrene-co-lithium maleate-co-2-phenyl-5-(4-vinylphenyl)oxazole] has been synthesized and characterized for thermal neutron detection and neutron/gamma-ray discrimination. The terpolymer was synthesized using solution-based free radical polymerization and had a composition by mass of 60.64% styrene, 31.64% maleic anhydride, and 7.72% 2-phenyl-5-(4-vinylphenyl)oxazole. The maleic anhydride groups were hydrolyzed and titrated with (LiOH)-Li-6 to form the lithiated terpolymer, resulting in a Li-6 content of 2.96% by mass. Monomer and polymer synthesis, film fabrication protocols, photoluminescence, and scintillation responses of this new scintillation material are reported. This approach demonstrates a novel method by which mechanically robust and transparent Li-6-based polymer films can be produced. (C) 2014 Elsevier Ltd. All rights reserved.
