Abstract

Nanoparticles of tungsten oxide (WO) and zinc oxide (ZnO) enriched polyethylene sebacate (PES) nanocomposites were prepared through the coprecipitation process and condensation polymerization reaction. The obtained nano-sized particles of WO and ZnO, PES, and nanocomposites (WO-PES NC and ZnO-PES NC) were investigated. The average molecular weight of the cured PES was measured by employing the gel permeation chromatography (GPC) technique. Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) spectra assured the formation of the polymeric nanocomposites.WO and ZnO nanoparticles supposed a condensed porous spherical phase found implanted in the polymer structure, as detected by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) methods. These nano-scale systems achieved an electrical activity based on the conductive nanoparticles embedded matrix as a result of the ion-ion interactions. The microbial influence of the nanocomposites was examined against pathogenic bacteria; and , and Fungi; and . Results exhibited that these nanocomposites have antimicrobial effects from moderate to slightly high on bacteria and high on fungi which was confirmed by a clear zone of inhibition. This study contributes to the design of reasonable composites to be under evaluation for their catalytic effect.

摘要

通过共沉淀法和缩聚反应制备了富含氧化钨(WO)和氧化锌(ZnO)的聚癸二酸乙二酯(PES)纳米复合材料颗粒。对所获得的WO和ZnO纳米颗粒、PES以及纳米复合材料(WO-PES NC和ZnO-PES NC)进行了研究。采用凝胶渗透色谱(GPC)技术测定了固化PES的平均分子量。傅里叶变换红外光谱(FTIR)和X射线衍射(XRD)光谱证实了聚合物纳米复合材料的形成。通过扫描电子显微镜(SEM)和透射电子显微镜(TEM)方法检测发现,WO和ZnO纳米颗粒呈现出一种凝聚的多孔球形相,植入在聚合物结构中。由于离子-离子相互作用,这些纳米级体系基于嵌入基质的导电纳米颗粒实现了电活性。考察了纳米复合材料对病原菌的抗菌作用,包括细菌;以及真菌;以及。结果表明,这些纳米复合材料对细菌具有中度到略高的抗菌效果,对真菌具有高抗菌效果,抑菌圈清晰证实了这一点。本研究有助于设计合理的复合材料,以评估其催化效果。
