Summary In this study poly(dimethylsiloxane) (PDMS) nanocomposites with 1wt % of zinc oxide (ZnO) and 1wt % of silanized ZnO nanoparticles were prepared through cross‐linking reaction. The prepared samples were irradiated under vacuum at room temperature with a 2 MeV proton beam with fluences in the 10 13 –10 15 cm −2 range. The influence of nanoparticles on the cross‐linking processes and structural degradation of irradiated PDMS nanocomposites was investigated using Raman and Fourier transform infrared spectroscopy (ATR). The analysis of vibrational spectra has shown that prepared PDMS nanocomposites have higher resistance to proton irradiation in comparison to pristine PDMS. Under the highest proton irradiation fluence (10 15 cm −2 ) PDMS with 1 % ZnO provided the best radiation protection.
