Production, Optical Properties, and Wettability of Two-Sided Films Based on Silver–Sorbitan Monoleate Nanocomposite

Different redispersate solutions of a silver–sorbitan monooleate nanocomposite in n -heptane with silver concentration of 8 × 10 −5 –1 × 10 −3 M are used to obtain thin double-sided silver films on glass and quartz substrates. Photon correlation spectroscopy is used to show that the size of particles in solutions varies in the range of 9–90 nm. The films are characterized via atomic absorption, spectrophotometry, measuring angles of wetting, and scanning electron microscopy. The plasmon absorption of silver (λ = 402–440 nm) is confirmed for films obtained in (0.8–2) × 10 −4 M solutions, and after subjecting all films to heat treatment at 200°C.
