Investigation on Application of Biomimetic Technology to the Conservation of Longmen Grottoes

A biomimetic approach using calcium oxalate to protect historic stone structures, including the UNESCO World Heritage Site Longmen Grottoes, shows promising results. Laboratory experiments demonstrated that a protective film formed on marble stone effectively resists soil and acid weathering, while field trials at Longmen Grottoes validated its practical application. Characterization via XRD and SEM confirmed the material's stability and effectiveness, suggesting this method could significantly advance the conservation of vulnerable cultural heritage sites.
