Abstract: It is proposed that silver–sorbitan monooleate composite be used to obtain concentrated silver organosols. The composite is prepared by reducing silver nitrate with hydrazine in a dynamic emulsion of sorbitan monooleate in ethyl acetate. The content of silver (75%) and surfactant (25%) in the composite is determined by means of atomic absorption, differential thermal analysis, and microanalysis. It is shown via XRD phase analysis and photon-correlation spectroscopy that the size of silver particles in the composite is 5–6 nm. Organosol of silver nanoparticles (0.2 M) is obtained through ultrasonic redispersion of the composite in heptane. Conductive films on glass substrates are formed after drying the organosol and subjecting it to heat treatment at 200С. According to data obtained via scanning electron microscopy, the film is 500 nm thick.
