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.

期刊介绍： An International Journal Devoted to Electrochemical Aspects of Biology and Biological Aspects of Electrochemistry Bioelectrochemistry is an international journal devoted to electrochemical principles in biology and biological aspects of electrochemistry. It publishes experimental and theoretical papers dealing with the electrochemical aspects of: • Electrified interfaces (electric double layers, adsorption, electron transfer, protein electrochemistry, basic principles of biosensors, biosensor interfaces and bio-nanosensor design and construction. • Electric and magnetic field effects (field-dependent processes, field interactions with molecules, intramolecular field effects, sensory systems for electric and magnetic fields, molecular and cellular mechanisms) • Bioenergetics and signal transduction (energy conversion, photosynthetic and visual membranes) • Biomembranes and model membranes (thermodynamics and mechanics, membrane transport, electroporation, fusion and insertion) • Electrochemical applications in medicine and biotechnology (drug delivery and gene transfer to cells and tissues, iontophoresis, skin electroporation, injury and repair). • Organization and use of arrays in-vitro and in-vivo, including as part of feedback control. • Electrochemical interrogation of biofilms as generated by microorganisms and tissue reaction associated with medical implants.
