Abstract

Abstract : Boron–lithium imidazolate frameworks with high thermal stability and excellent resistance capacity exhibit efficient neutron radiation shielding property. Abstract : Radiation protective materials are widely applied to avoid occupational hazards from either particle emissions or high-energy electromagnetic waves. Herein, we present a boron imidazolate framework (BIF) as a novel neutron shielding additive with high neutron capture cross-section elements B/Li and H. The BIF1-based epoxy resin matrix (Ep-BIF1) possesses high thermal stability and excellent resistance capacity. The neutron radiation shielding property was characterized using an Am–Be source, in which the thermal neutron shielding efficiency of Ep-BIF1 is notably higher than that of Ep-B4 C with equal boron concentration, showing potential applications as an advanced efficient neutron radiation shielding composite.
