Design of a double-layered material as a long-acting moisturizing hydrogel–elastomer and its application in the field protection of elephant ivories excavated from the Sanxingdui Ruins

Year: 2024

Type: article

Abstract: . Based on these properties, we used the prepared P(AM-AA)/PDMS double-layer material directly for wrapping the K8 ivory with the highest water content at Sanxingdui. The weight retention rate of the ivory was around 70% after 50 days of placement (temperature: 25 °C; relative humidity: 60% RH), the macroscopic morphology did not change significantly and the mechanical properties of the wrapped ivory were basically unchanged, which indicated that the double-layer material has an excellent on-site protection effect on the ivory excavated from Sanxingdui. This work provides new ideas and methods for the temporary conservation of wet heritage.
