“…By controlling the fluidity, the tuned chemical nature of the polymer can enhance the polymer-metal interaction, and this could lead to an exciting organization of particulate films. So, the polymer-metal interaction can be tuned by selecting an inert polymer as a substrate [7], modifying the polymer characteristics by electron beam irradiation [6], and also by the blending of an inert-polymer-like polystyrene with an interacting polymer like poly (4-vinyl pyridine) [8]. The other way to tune the metal-polymer interaction and enhance the properties is by selecting a polymer with an interacting side molecular group [9].…”

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