Nowadays, aqueous cleaning systems are preferred for the cleaning of painted artifacts because they are environmental friendly and offer several advantages in terms of selectivity and gentle removal of undesired materials. However, materials interaction with water can lead to mechanical stress between the substrate and the paint layers. The confinement of water cleaning systems in a hydrogel with high retention capability can limit this disadvantage. Hence, the aim of this work was to develop novel chemical hydrogels, specifically designed for the cleaning of water-sensitive painted artifacts. These are based on highly hydrophilic semi-interpenetrating p(HEMA)/PVP networks with suitable mechanical strength to avoid gel residues after cleaning treatment. To assess on the potential of these novel hydrogels their release and retention properties were compared with the widely used agar-agar hydrogel.

Abstract

Nowadays, aqueous cleaning systems are preferred for the cleaning of painted artifacts because they are environmental friendly and offer several advantages in terms of selectivity and gentle removal of undesired materials. However, materials interaction with water can lead to mechanical stress between the substrate and the paint layers. The confinement of water cleaning systems in a hydrogel with high retention capability can limit this disadvantage. Hence, the aim of this work was to develop novel chemical hydrogels, specifically designed for the cleaning of water-sensitive painted artifacts. These are based on highly hydrophilic semi-interpenetrating p(HEMA)/PVP networks with suitable mechanical strength to avoid gel residues after cleaning treatment. To assess on the potential of these novel hydrogels their release and retention properties were compared with the widely used agar-agar hydrogel.
