Antimicrobial polymeric coatings rely not only on their surface functionalities but also on nanoparticles (NPs). Antimicrobial coatings gain their properties from the addition of NPs into a polymeric matrix. NPs that have been used include metal-based NPs, metal oxide NPs, carbon-based nanomaterials, and organic NPs. Copper NPs and silver NPs exhibit antibacterial and antifungal properties. So, when present in coatings, they will release metal ions with the combined effect of having bacteriostatic/bactericidal properties, preventing the growth of pathogens on surfaces covered by these nano-enhanced films. In addition, metal oxide NPs such as titanium dioxide NPs (TiO NPs) and zinc oxide NPs (ZnONPs) are used as NPs in antimicrobial polymeric coatings. Under UV irradiation, these NPs show photocatalytic properties that lead to the production of reactive oxygen species (ROS) when exposed to UV radiation. After various forms of nano-carbon materials were successfully developed over the past decade, they and their derivatives from graphite/nanotubes, and composite sheets have been receiving more attention because they share an extremely large surface area, excellent mechanical strength, etc. These NPs not only show the ability to cause oxidative stress but also have the ability to release antimicrobial chemicals under control, resulting in long-lasting antibacterial action. The effectiveness and life spans of the antifouling performance of a variety of polymeric materials have been improved by adding nano-sized particles to those coatings.
抗菌聚合物涂层不仅依赖于其表面功能，还依赖于纳米颗粒（NPs）。抗菌涂层通过将纳米颗粒添加到聚合物基质中而获得其性能。已使用的纳米颗粒包括金属基纳米颗粒、金属氧化物纳米颗粒、碳基纳米材料和有机纳米颗粒。铜纳米颗粒和银纳米颗粒具有抗菌和抗真菌特性。因此，当它们存在于涂层中时，会释放金属离子，具有抑菌/杀菌特性的综合作用，防止病原体在这些纳米增强薄膜覆盖的表面上生长。此外，金属氧化物纳米颗粒，如二氧化钛纳米颗粒（TiO NPs）和氧化锌纳米颗粒（ZnONPs），被用作抗菌聚合物涂层中的纳米颗粒。在紫外线照射下，这些纳米颗粒表现出光催化特性，当暴露于紫外线辐射时会产生活性氧（ROS）。在过去十年成功开发出各种形式的纳米碳材料之后，它们以及来自石墨/纳米管和复合片材的衍生物受到了更多关注，因为它们具有极大的表面积、优异的机械强度等。这些纳米颗粒不仅表现出引起氧化应激的能力，还具有可控释放抗菌化学物质的能力，从而产生持久的抗菌作用。通过向各种聚合物材料涂层中添加纳米尺寸的颗粒，提高了其防污性能的有效性和寿命。
