Abstract:
Marine biofouling and corrosion are serious impediments to the promotion and development of the marine industry. The short service life and limited application of single coatings have greatly increased the economic burden on the industry. The development of multi-functional composite coatings has become a particularly pressing issue. The combination of Cu-BTC and Ti3C2Tx as a specific resin filler represents a new strategy (Ti3C2Tx@Cu-BTC@EP). HAADF-STEM, PXRD and XPS were used to verify the successful synthesis of the materials. Ti3C2Tx@Cu-BTC@EP was able to achieve 100 % lethality of E. coli under the condition of light exposure within 24 h. In addition, the impedance modulus of the coating in the low-frequency range was increased by about 3.15 times compared to the blank group with the addition of 1 wt% filler, reaching as high as 7.06 × 108 Ω. Overall, the novel Ti3C2Tx@Cu-BTC@EP composite coating is expected to promote new advances in epoxy resin research.
