Effect of silane/amine-based dopants on polymer-metal interaction of sub-surface silver nanoparticulate films

Abstract The optical and morphological properties of the vacuum-evaporated silver (Ag) nanoparticulate films on softened polyvinyl alcohol (PVA) modified with 3-mercaptopropyl trimethoxysilane (MPTMS) 3-aminopropyl (APTMS) dopants are reported. topography particulate is characterized by field-emission scanning electron microscopy. spectra broadening, red-shift, increase in intensity values plasmonic resonance peak nature dopant have a strong dependence particle size, shape, inter-particle separation. conducted experimental studies supported Finite Difference Time-Domain (FDTD) simulation results. Quantitative analysis Fourier-Transform Infrared Spectroscopy (FTIR) Raman confirm surface modification Ag doped PVA substrates. amount polymer-metal interaction caused strongly interacting silane groups their influence morphology discussed.
