Abstract EN
Cross-linking degree of a poly(dimethylsiloxane) (PDMS) film was controlled, and the incorporation of hydrophobic decanethiol-passivated gold (Au) nanoparticles into the film was investigated.
FT-IR spectra indicated that the hydrosilylation reaction between a vinyl group and a hydrosilyl group occurred with the cross-linking.
The swelling degree of the film in toluene changed with a cross-linker concentration, indicating the control of the cross-linking degree of PDMS film.
By EDX analysis, the amount of incorporated Au nanoparticles increased with decreasing a cross-linker concentration, indicating the enlarged free volume of the film.
The Au nanoparticle-PDMS composite film containing a cross-linker at 6 wt% showed brown color attributed to plasmon resonance of Au nanoparticles, suggesting the Au nanoparticles in the film at monodispersion state.
The UV-visible absorbance of the composite film decreased without spectralshift by swelling with toluene, and the changes were reversible.
The aggregation among Au nanoparticles in the composite film after calcination also depended on the cross-linking degree.
Thus, the control of cross-linking degree of PDMS film successfully leaded to a simple way of fabricating the Au nanoparticle-PDMS composite film at the mono-dispersion state.
