Effect of yttrium phosphate on irradiation of methyl vinyl silicone rubber

Nanoscale Yttrium phosphate (YPO4) particles was prepared by hydrothermal method, and was used as anti-radiation additive for methyl vinyl silicone rubber (MVQ rubber). The mechanical properties and crosslink density of YPO4/MVQ rubber nanocomposites before and after irradiated by γ-rays were determined. The irradiation protection mechanism of YPO4 was discussed using the fluorescence spectra. The results showed that YPO4 could improve the irradiation-resistant properties of silicone rubber.
