Abstract

In the current work, films of PS/SiO₂–CeO₂ futuristic nanocomposites were fabricated to apply in numerous nanoelectronics, energy storage and biomedical fields. The microstructure, morphological and dielectric features of PS/SiO₂–CeO₂ films were investigated. The obtained results showed that the dielectric constant increased from 3.13 to 3.94 with the increase of (SiO₂–CeO₂) NPs content at 100 Hz and its decreased with the increase of frequency, while the electrical conductivity was increased to 1.53E-11 S/cm with the increase of (SiO₂–CeO₂) NPs content at 100 Hz and its increased with the increase of frequency. These results are welcomed in many energy storage and nanoelectronic applications The antibacterial application of PS/SiO₂–CeO₂ nanocomposites were tested against both Gram-positive(Staphylococcus aureus) and Gram-negative (Escherichia coli). The obtained result was that the diameter of the inhibition zone was increased with the increase of (SiO₂–CeO₂) NPs content. Finally, the PS/SiO₂–CeO₂ nanocomposite showed excellent dielectric properties and high activity for antibacterial compared with other nanocomposites which make them as promising materials for energy storage and biomedical fields.

PS/ SiO2-CeO2纳米结构储能与抗菌性能的研究

在目前的工作中，制备了PS/ SiO2-CeO2未来纳米复合材料薄膜，用于许多纳米电子学，储能和生物医学领域。研究了PS/ SiO2-CeO2薄膜的微观结构、形态和介电特性。结果表明：在100 Hz时，介电常数随（SiO2-CeO2） NPs含量的增加从3.13增加到3.94，随频率的增加而减小；在100 Hz时，电导率随（SiO2-CeO2） NPs含量的增加而增加到1.53E-11 S/cm，随频率的增加而增加。研究了PS/ SiO2-CeO2纳米复合材料对革兰氏阳性菌（金黄色葡萄球菌）和革兰氏阴性菌（大肠杆菌）的抗菌作用。结果表明，随着（SiO2-CeO2） NPs含量的增加，抑制带的直径增大。最后，与其他纳米复合材料相比，PS/ SiO2-CeO2纳米复合材料具有优异的介电性能和较高的抗菌活性，在储能和生物医学领域具有广阔的应用前景。
