Monolayers of Surfactants Containing Nanoparticles of Hexacyanoferrates of Various Metals

Abstract

In this article the possibility of obtaining Langmuir-Blodgett films on the basis of octadecylamine monolayers containing nanoparticles of hexacyanoferrates of various metals was shown. A comparison was made between different methods for obtaining these particles. Nanoparticles were produced using sodium hexametaphosphate as a stabilizer, their average size were determined by laser diffraction. The isotherms of compression were studied for monolayers on a subphase containing nanoparticles. Optimal conditions for the transfer of monolayers to a solid substrate were chosen according to the data obtained and their morphology was studied by scanning electron microscopy. The cyclic voltammetry method also confirmed the successful transfer of a monolayer to a solid substrate and showed the manifestation of the electrochemical properties of the obtained substrates.
