Gels for the Conservation of Cultural Heritage
Published online by Cambridge University Press: 20 January 2012
The consolidation of a pictorial surface or the removal of undesired material from the surface of an artifact, are the most important and delicate operations in the conservation of cultural heritage. In this contribution we report on the synthesis and characterization of two innovative systems for the cleaning of works of art: i) highly viscous polymeric dispersions (HVPDs) of poly(vinyl alcohol-co-vinyl acetate) random copolymer (PVAc), and ii) chemical gels from acrylamide - N,N’-methylene bisacrylamide, loaded with innovative aqueous cleaning systems. These systems were prepared, characterized and tested over artistic surfaces, such as wood and canvas. Rheology and FTIR spectroscopy allowed the characterization of the materials, and provided evidence that the systems allow an efficient cleaning of the substrates, without leaving residues.
