Abstract

Abstract: With the rapid development of nuclear technology application industry, higher requirements are put forward for the types, service environments and structural properties of neutron radiation protection materials. B₄C/PI composite material was prepared for the development of functional/structural integrated neutron radiation protection materials. Boron carbide is an important neutron radiation shielding material with high shielding efficiency. B₄C particles were selected as additive particles, and silane coupling agent KH550 was used to functionalize B₄C particles to improve the dispersion of particles in polyimide matrix, and B₄C/PI composites were successfully prepared. The results show that B₄C/PI composite has good neutron radiation shielding performance, mechanical properties and thermal stability. When the content of B₄C is 10%, the composite exhibits excellent properties. At 680 ℃, the residual mass of the composite is 70.674%, thermal neutron shielding rate is 62.36%, and tensile strength is 57.27 MPa. It shows great application potential for materials requiring high thermal stability and neutron radiation shielding, such as fusion reactor systems and nuclear waste disposal.

Key words: polyimide, neutron shielding, thermal stability, mechanic properties
