Oracle bones are artifacts of great significance and value in the study of Chinese history and culture. Because of soil and bacterial erosion, bones become fragile, and the inscriptions on the surface become blurred, resulting in the loss of historical information on the bones. In early times, scholars often used adhesives for bonding and reinforcement, whereas in modern times, organic and inorganic materials have been used as reinforcement for oracle bones. In this study, the surface of oracle bone was protected and reinforced by a new silicone coupling reagent that could self-polymerize in the format of colorless solution with good antimicrobial properties. The DESPMA was applied to the surface of oracle bone by dropwise addition and curing, effectively protecting it from bacteria and slowing down the yellowing process. The results showed that the reagent could significantly improve the antimicrobial properties of bone samples and reduce the yellowing and discoloration caused by bacterial attack. The reagent barely affected the appearance of the bone samples. These findings are promising and valuable for effective application in bone protection and utilization.
