| Popis: | Composites of natural rubber and boron carbide with different concentrations were prepared as thermal neutron radiation shielding materials. The maximum degree of swelling ( Q ), the penetration rate ( P ) and the average diffusion coefficient ( D av ) were studied. Using the Flory–Rehner equation, the crosslinking densities of the investigated samples were obtained. The effect of thermal oxidative aging on both the swelling behaviour and crosslinking density was also investigated. |
