Electrochemical Evaluation of a Recycled Copolymer Coating for Cultural Heritage Conservation Purposes

الملخص EN

Acrylonitrile-butadiene-styrene (ABS) is a well-known discard product from the industry.

This copolymer can be dissolved in organic solvents, and thin films can be created by immersion.

Two requirements for coatings used for cultural heritage conservation purposes are transparency and reversibility, both fulfilled by ABS films.

The aim of this work was to characterize the copolymer and to evaluate the electrochemical properties of ABS coatings applied to copper.

Such performance was compared to that of a commercial varnish commonly used in conservation.

The results indicate high protection values of the ABS film, generating a potential application for this waste material.

The electrochemical techniques included electrochemical noise, impedance spectroscopy, and potentiodynamic polarization.
