In this study, we synthesized a new organic-inorganic hybrid material based on N-halamine and TiO₂ using miniemulsion polymerization. N-halamine as a broad-spectrum antimicrobial agent has a more powerful inactivation ability over other agents. The novel TiO₂ based nanocomposites (MPS-TiO₂@PVBC-DMH-Cl NPs) demonstrated significantly enhanced UV stability, potent antibacterial and antifungal activities. Upon addition of a certain amount of the nanoparticles into commercial water-based latex paints as UV-stable antibacterial additives, the prepared paint successfully prevented biofilm formation against model microbe cells. The prepared paint was also stable under UV exposure, and readily rechargeable if efficacies were lost under challenging conditions.

在这项研究中，我们使用细乳液聚合合成了一种基于N-卤胺和TiO ₂的新型有机-无机杂化材料。N-卤胺作为一种广谱抗菌剂，具有比其他药剂更强大的灭活能力。新型的基于TiO ₂的纳米复合材料（MPS-TiO ₂ @ PVBC-DMH-Cl NPs）表现出显着增强的UV稳定性，有效的抗菌和抗真菌活性。在将一定量的纳米颗粒作为紫外线稳定的抗菌添加剂添加到商用水性乳胶涂料中后，制得的涂料成功地防止了针对模型微生物细胞的生物膜形成。所制备的涂料在紫外线下也很稳定，如果在苛刻的条件下失去效能，则很容易充电。
