Abstract

The antibacterial activity of biomedical polymer materials is an important basis for their resistance to biofilm contamination as implantable medical devices. However, developing durable and stable antibacterial composites through a universal manufacturing method remains a challenge. Herein, based on an organic–inorganic synergistic antibacterial strategy, functional nanoparticles with high antibacterial performance and better polymer compatibility were prepared by combining zinc oxide nanoparticles (ZnO NPs) with quaternary ammonium compound 3-(trimethoxysilyl)-propyldimethyloctadecyl ammonium chloride (QAS), which containing siloxane group. The ZnO-QAS nanoparticles were then introduced to low-density polyethylene (LDPE) by simple melt blending to manufacture synergistic antibacterial composites. The organic–inorganic hybrid strategy significantly improved the antibacterial activity of the composites, the PE/ZnO-QAS composites possess satisfactory antibacterial efficiency of 99.9% and 99.75% against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), respectively, and it could effectively inhibit biofilms. In addition, the functionalization of organic compound QAS provides excellent polymer compatibility for ZnO NPs, which is conducive to their uniform dispersion in LDPE, and comprehensively improves the thermal stability, mechanical properties, and crystallinity of the composites. This provides potential application value for the preparation of long-term stable antibacterial biomedical materials.

制备用季铵盐功能化氧化锌纳米颗粒改性的低密度聚乙烯有效抗菌复合材料
生物医学聚合物材料的抗菌活性是其作为植入式医疗器械抗生物膜污染的重要基础。然而,通过通用制造方法开发持久稳定的抗菌复合材料仍是一项挑战。本文基于有机-无机协同抗菌策略,将氧化锌纳米颗粒(ZnO NPs)与含有硅氧烷基团的季铵盐化合物 3-(三甲氧基硅基)-丙基二甲基十八烷基氯化铵(QAS)结合,制备出了具有高抗菌性能和更好聚合物相容性的功能纳米颗粒。然后通过简单的熔融混合将 ZnO-QAS 纳米粒子引入到低密度聚乙烯(LDPE)中,制造出协同抗菌复合材料。有机-无机杂化策略显著提高了复合材料的抗菌活性,PE/ZnO-QAS复合材料对大肠杆菌和金黄色葡萄球菌的抗菌效率分别达到99.9%和99.75%,并能有效抑制生物膜。此外,有机化合物 QAS 的官能化为 ZnO NPs 提供了良好的聚合物相容性,有利于其在低密度聚乙烯中的均匀分散,并全面提高了复合材料的热稳定性、机械性能和结晶度。这为制备长期稳定的抗菌生物医学材料提供了潜在的应用价值。

期刊介绍: Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology. As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including: polymer synthesis; polymer reactions; polymerization kinetics; polymer physics; morphology; structure-property relationships; polymer analysis and characterization; physical and mechanical properties; electrical and optical properties; polymer processing and rheology; application of polymers; supramolecular science of polymers; polymer composites.
