With the continuous development of the marine economy and the upgrading of marine infrastructure, the increasing marine engineering equipment is facing a serious problem of marine fouling. However, developing marine antifouling materials and antifouling technologies is extremely difficult due to the complexity of the marine environment and the biodiversity of the fouling. Therefore, it is the key breakthrough to develop advanced materials for solving marine fouling problems. Nanomaterials with small dimensions and controlled micro-structure have outstanding antifouling efficiency and great promise for various antifouling fields. Herein, the development of antifouling nanomaterials and technologies in recent years are reviewed for aspects of types of antifouling nanomaterials, technologies of antifouling, and potential application of antifouling. The antifouling nanomaterials are categorized as non-metal-based nanomaterials, metal-based nanomaterials, polymeric nanomaterials, composite nanomaterials, and others. Additionally, the potential applications of antifouling nanomaterials, including marine antifouling, water treatment, and medical antifouling are discussed. Finally, we proposed the perspectives of research and development trends of the antifouling nanomaterials. This overview may promote the development of new efficient antifouling nanomaterials and develop their potential commercial applications.

Epoxy resin powder coating has been successfully applied on the corrosion protection of magnesium lithium alloys. However, poor wear resistance and microcracks formed during the solidification have limited it extensive application. There are limited approaches to exploit such anti-corrosion and mechanical properties of magnesium lithium alloys. Herein, the epoxy resin powder coating with polydopamine modified molybdenum disulfide (MoS₂@PDA-EP powder coating with 0, 0.1, 0.2, 0.5, 1.0 wt.% loading) was well prepared by melt extrusion to investigate its anticorrosion performance and wear resistance. The results revealed that the addition of MoS₂@PDA enhanced the adhesion strength between coatings and alloys, wear resistance and corrosion protection of the powder coatings. Among them, the optimum was obtained by 0.2 wt.% MoS₂@PDA-EP powder coating which could be attributed to well dispersion and efficient adhesion with coating matrix. To conclude, MoS₂@PDA-EP powder coating is meaningfully beneficial for the anticorrosive and wear performance improvement of magnesium lithium alloys.
