Raman spectra of poly(dimethylsiloxane) nanocomposites,
In this research PDMS network was prepared by cross-linking based on hydrosilylation. Cross-linked PDMS nanocomposites were prepared with different fractions of detonated nanodiamond (DND) and onion-like carbon (OLC) nanoparticles (0, 1, 2 and 5 wt %). The structure and vibrational dynamics of cross-linked PDMS nanocomposites was investigated by micro-Raman spectroscopy. The knowledge of the vibrational properties of prepared nanomaterials is of fundamental importance to the understanding of the influence of embedded nanoparticles on the process of polymerization and cross-linking. The analysis of Raman spectra of PDMS nanocomposites is based on the assignment of vibrational spectra of cross-linked PDMS nanocomposites and comparison with spectra of pure PDMS as well as with spectrum of DND or OLC nanoparticles. Changes in vibrational spectra of PDMS due to the inclusion of different fraction of nanoparticles were also used to explain the interaction in the interface and the effect of presence of nanoparticles on the polymer network structure.
