However, MOC possesses inherent limitations, such as low strength and poor water resistance, which restrict its application in construction and wood adhesives. To overcome these challenges, we developed a biomimetic organic–inorganic hybrid cement material (MOC-TA-AS), inspired by the adhesion mechanism of marine barnacles. Tannic acid (TA) and acorn powder (AS) were incorporated as organic components to provide additional active sites for Mg<sup>2+</sup> ions in MOC, forming a stable double-chelate network. The MOC-TA-AS composite showed significant improvements over MOC-based materials, including a 14% increase in compressive strength (109.79 MPa after 28 days of curing) and a 57.8% improvement in water resistance coefficient compared to the control. After water immersion, the content of the 5-phase increased by 72.8% (MOC-AS/1.5-TA/0.8), while the Mg(OH)<sub>2</sub> content decreased by 25.8%. These improvements are attributed to the weak acidity and catechol structure of tannic acid, which promote the formation of a gel-like 5-phase structure. Additionally, the large dendritic starch structure of acorn powder, in conjunction with tannic acid, helped create a chelating network. The protective coating provided by TA and AS to the 5-phase products, along with their chelation with Mg<sup>2+</sup> ions, was also investigated.
