The Study of Polydimethylsiloxane-nanodiamond Composite Exposed to Proton Radiation
The vibrational dynamics of pure PDMS and PDMS-DND nanocomposites, both nonirradiated and irradiated samples, were investigated using Raman, photoluminescence (PL) and FTIR spectroscopies. The Raman and FTIR spectra of the PDMS and PDMS-DND composites exhibit an overall reduction in intensity of all vibrational bands following irradiation. The changes in the relative intensities of the characteristic vibrational bands as a function of irradiation fluence indicate that cleavage of the backbone Si–O–Si chains was most pronounced. The analysis has shown that structural degradation of PDMS-DND composites takes place at an order of magnitude higher fluence than for pure PDMS. Thus, the nanocomposite material exhibits enhanced stability against high energy proton irradiation as compared to pure PDMS. These results provide additional prospective for use of DND-based polymer composites for applications in high radiation environments.
