Abstract

Microbiologically influenced corrosion (MIC) poses considerable challenges in various industries, prompting the exploration of advanced materials to mitigate microbial threats. This study successfully synthesized nanoscale vermiculite (VMT) from natural seawater and utilized it as a foundation to integrate magnetic nanoparticles (Fe₃O₄) and chlorhexidine acetate (CA) for inhibiting MIC. A comprehensive investigation encompassing the synthesis, characterization, and application of these VMT/Fe₃O₄/CA composites was conducted to evaluate their antimicrobial effectiveness against Escherichia coli, Staphylococcus aureus, and sulfate-reducing bacteria (SRB), demonstrating an efficacy exceeding 99.5%. Moreover, the composite material demonstrated the capability to align with a magnetic field, enabling precise drug targeting and release, thereby facilitating biofilm removal. This research makes a significant contribution to the advancement of intelligent, efficient, and eco-friendly corrosion protection solutions.

二维复合矿物质的靶向输送用于清除生物膜

受微生物影响的腐蚀（MIC）给各行各业带来了巨大的挑战，促使人们探索先进的材料来减轻微生物的威胁。本研究成功地从天然海水中合成了纳米级蛭石（VMT），并以此为基础整合了磁性纳米颗粒（Fe3O4）和醋酸洗必泰（CA），用于抑制 MIC。研究人员对这些 VMT/Fe3O4/CA 复合材料的合成、表征和应用进行了全面调查，评估了它们对大肠杆菌、金黄色葡萄球菌和硫酸盐还原菌 (SRB) 的抗菌效果，结果表明其功效超过 99.5%。此外，这种复合材料还具有与磁场对齐的能力，可实现精确的药物靶向和释放，从而促进生物膜的清除。这项研究为推动智能、高效和生态友好型腐蚀防护解决方案的发展做出了重大贡献。
