In this article, the synthesis, optical, and electrical properties of composites consisting of polyethylene oxide (PEO), carboxymethyl cellulose (CMC), and titanium dioxide nanoparticles are examined. Flexible nanocomposite samples comprising PEO, CMC, and TiO nanoparticles were produced swiftly via using the cast synthesis method. In addition, XRD and FT-IR analysis were performed in order to analyze the structures of the prepared samples. Our results demonstrate the PEO/CMC blend's effectiveness in interacting with TiO nanoparticles. The optical properties of the PEO/CMC and nanocomposite samples, such as the energy band gap, were studied using the UV/Vis optical absorbance. It was found that as TiO NP weight fraction increases, the energy gap narrows. Moreover, TiO nanoparticles with an average size of 16 nm were formed in spherical and rod shapes, according to a TEM image. The SEM images demonstrate how the distribution of TiO NPs increased upon the surfaces of the prepared films. The antibacterial activity in the nanocomposites was shown to be enhanced by the TiO NP concentrations. Finally, we proposed that PEO/CMC-0.8 wt. % TiO nanocomposites with enhanced optical, electrical, and dielectric properties should be used in electrochemical devices.
在本文中，对由聚环氧乙烷（PEO）、羧甲基纤维素（CMC）和二氧化钛纳米颗粒组成的复合材料的合成、光学和电学性能进行了研究。通过浇铸合成法快速制备了包含PEO、CMC和TiO纳米颗粒的柔性纳米复合材料样品。此外，为了分析所制备样品的结构，进行了X射线衍射（XRD）和傅里叶变换红外光谱（FT-IR）分析。我们的结果证明了PEO/CMC共混物与TiO纳米颗粒相互作用的有效性。使用紫外可见（UV/Vis）光吸收研究了PEO/CMC和纳米复合材料样品的光学性能，如能带隙。结果发现，随着TiO纳米颗粒重量分数的增加，能隙变窄。此外，根据透射电子显微镜（TEM）图像，平均尺寸为16 nm的TiO纳米颗粒呈球形和棒状形成。扫描电子显微镜（SEM）图像展示了TiO纳米颗粒在制备薄膜表面的分布是如何增加的。纳米复合材料中的抗菌活性显示出随着TiO纳米颗粒浓度的增加而增强。最后，我们提出具有增强光学、电学和介电性能的PEO/CMC-0.8 wt.% TiO纳米复合材料应用于电化学器件。
