摘要

Boron carbide/natural rubber latex (B4C/NRL) flexible films were prepared via dip-molding with B4C content in the range of 5-55 wt% for thermal neutron (0.0253 eV) shielding. B4C was well dispersed in NRL according to microscopic observation. Both the inside and outside surfaces of the film were smooth. For B4C/NRL flexible films, the minimum elongation at break was greater than 600%, the minimum tensile strength was greater than 12 MPa, and the hardness was in the range of 35-55 HA, which were suitable for preparing flexible wearable products. The attenuation efficiencies of the B4C/NRL flexible films for thermal neutrons were also calculated. The B4C/NRL flexible films exhibit good attenuation effect for thermal neutrons.
