Abstract

In this work, we have synthesized and discussed the results of electrosynthesis of metal-polymer nanocomposites of gold. Nanocoatings were made on pure iron and steel electrodes by combining the process of electropolymerization of 1-vinyl-1.2.4-triazole with crotonic acid and cathodic deposition of gold. Using UV, IR and atomic absorption spectroscopies, X-ray phase analysis, as well as thermogravimetric and elemental analyses, the structure and composition of the synthesized nanocomposites and nanocomposite coatings were studied.

Highlights

Nanocomposite materials containing gold nanoparticles have unique properties and their development is promising for medicine, nanophotonics and catalysis [1,2,3,4]
In the electronic spectra of gold-containing nanocomposites, in contrast to aqueous solutions of the initial copolymers and HAuCl4, plasmon absorption bands appear with a maximum in the region of nanocomposite coatings containing gold
When passing from copolymers to nanocomposites with gold nanoparticles, it can be seen that the number of nonionized carboxyl groups (–СООH) decreases significantly, and a new absorption band appears at 1577 cm-1, which is characteristic of stretching vibrations of the carboxylate anion (–COOH-)

Summary

Introduction

Nanocomposite materials containing gold nanoparticles have unique properties and their development is promising for medicine, nanophotonics and catalysis [1,2,3,4].Electrosynthesis and study of the properties of functional polymers and on this basis obtained nanomaterials, is the most rapidly developing area of modern chemical science. These properties are characteristic for copolymers of 1-vinyl-1.2.4-triazole (VT) with acrylic acid, which are poorly studied, but promising polymers for medical use [13,14,15,16]. Nanocomposite materials containing gold nanoparticles have unique properties, and their use is promising for medicine [27,28,29].
