Here, we introduce for the first time a biomimetic conservation strategy based on volatile organic base modified inorganic ionic oligomers, which act as a dual-function agent for simultaneous deacidification and reinforcement. Triethylamine (TEA)-capped calcium phosphate oligomers (CPOs), stabilized at the molecular level, are utilized to ensure deep penetration into the cellulose fiber network. Upon application, the volatile TEA provides a transient and mild deacidification effect. As TEA is gradually removed, an in situ polymerization of the CPOs is subsequently initiated. Guided by the cellulose fibers of the paper as a natural template, these oligomers mineralize in situ into a continuous hydroxyapatite (HAP) network through inorganic ionic crosslinking, becoming intimately integrated with the paper structure. When tested on aged handmade bamboo paper, this integrated treatment yielded a neutral pH, a uniformly distributed alkaline reserve, and markedly improved tensile strength, all without altering the original appearance of the paper.
