EBS-TA@ZIF-67 Heterostructured Fillers for Enhanced Corrosion Protection and Fire Resistance of Waterborne Epoxy Coatings Xinying Huang (12261807) Chenyu Huang (3969329) Ruiqin Guo (22066246) Li Zhang (8200) Delong Xie (1404658) Xinxin Sheng (1685470) Space Science Medicine Physiology Pharmacology Environmental Sciences not elsewhere classified Chemical Sciences not elsewhere classified Plant Biology superior barrier capability nearly 2 orders enhanced corrosion protection electrochemical testing reveals exceptional corrosion resistance composite coating declines resulting composite coating wep coating increases neat wep coating waterborne epoxy coatings 67 heterostructured fillers composite coating waterborne epoxy fire resistance pristine wep tannic acid synergistic integration study demonstrates situ growth nacl solution magnitude relative flame retardancy fabricated via derived scaffolds 67 provides 42 days In this work, a tannic acid-functionalized EBS-TA@ZIF-67 (BTZ) heterostructure was fabricated via in situ growth of ZIF-67 onto etched basalt scales (EBS) premodified with tannic acid (TA). Subsequently, the as-prepared BTZ was incorporated into the waterborne epoxy (WEP) to formulate the composite coating. It is found that the resulting composite coating, containing only 0.4 wt % BTZ, exhibits substantially enhanced overall performance. Electrochemical testing reveals that after 42 days of exposure to 3.5 wt % NaCl solution, the |Z_0.01 Hz| value of the 4-BTZ/WEP coating increases by nearly 2 orders of magnitude relative to the neat WEP coating, highlighting its superior barrier capability. Furthermore, the peak heat release rate (PHRR) of the composite coating declines by 13.5% compared with the pristine WEP, reflecting markedly improved fire safety. This study demonstrates that the synergistic integration of basalt-derived scaffolds with ZIF-67 provides a viable pathway toward waterborne epoxy composite coatings with exceptional corrosion resistance and flame retardancy. 2026-09-29T00:00:00Z Text Journal contribution 10.1021/acs.iecr.6c03831.s001 https://figshare.com/articles/journal_contribution/EBS-TA_ZIF-67_Heterostructured_Fillers_for_Enhanced_Corrosion_Protection_and_Fire_Resistance_of_Waterborne_Epoxy_Coatings/34021093 CC BY-NC 4.0
