Abstract

The goal of this work is to produce nanocomposites films for energy-storing and optoelectronic applications by incorporating ceramic nanofiller into a polymer blend. By using the one-pot hydrothermal process, manganese ferrite nanoparticles (MnFe₂O₄ NPs) have been created. The produced NPs' size and morphology were verified by TEM, and the findings show that the particles are shape spherical and average size particles of around 21.45 nm. Using the casting approach, a series of polymer nanocomposites (PNCs) comprising carboxymethyl cellulose (CMC) and polyethylene oxide (PEO) have been created with various contents of MnFe₂O₄ NPs: 2.0, 5.0, 8.0, and 12.0 wt%. The XRD results, which display the changes in PNCs' microcrystalline properties, revealed a decline in the samples' degree of crystallinity. FTIR spectroscopy has been used to verify that PNCs are properly formed and that functional groups are present in the nanocomposites. Using a UV–Vis spectrophotometer, the optical properties were examined. The absorbance coefficient was calculated for each sample. As the nanoparticle content increased, so did the E_g decreased both direct and indirect of the PNCs. An increase in MnFe₂O₄ loading improved the thermal characteristics of the nanocomposites, indicating enhanced thermal stability of the films due to nanoparticle-to-CMC/PEO blend interaction. The adding of MnFe₂O₄ nanoparticles to the CMC/PEO matrix enhances the charge conduction mechanism, as seen by the doped samples' noticeably improved conductivity findings. As frequency increased, the dielectric loss (ε″) and dielectric constant (ε′) values decreased. The produced sample (8 % MnFe₂O₄/CMC/PEO) is the best option for energy-storing and optoelectronic applications like supercapacitors and sensors due to the structural changes and improvements made to the optical, thermal, and dielectric properties.

开发用于柔性储能和光学应用的羧甲基纤维素/聚环氧乙烷/MnFe2O4 纳米复合材料的介电、热、光学和电学特性

这项工作的目标是通过在聚合物混合物中加入陶瓷纳米填料，生产出用于储能和光电应用的纳米复合薄膜。通过采用一锅水热法工艺，制备出了锰铁氧体纳米粒子（MnFe2O4 NPs）。用 TEM 验证了所制得的 NPs 的尺寸和形态，结果表明这些颗粒呈球形，平均尺寸约为 21.45 nm。利用浇铸方法，制备了一系列由羧甲基纤维素（CMC）和聚氧化乙烯（PEO）组成的聚合物纳米复合材料（PNCs），其中 MnFe2O4 NPs 的含量各不相同：2.0、5.0、8.0 和 12.0 wt%。显示 PNC 微晶特性变化的 XRD 结果表明，样品的结晶度有所下降。傅立叶变换红外光谱用于验证 PNC 是否正确形成，以及纳米复合材料中是否存在官能团。使用紫外可见分光光度计检测了光学特性。计算了每个样品的吸光系数。随着纳米粒子含量的增加，PNCs 的直接和间接 Eg 值也随之降低。MnFe2O4 含量的增加改善了纳米复合材料的热特性，表明由于纳米粒子与 CMC/PEO 的相互作用，薄膜的热稳定性得到了提高。在 CMC/PEO 基体中添加 MnFe2O4 纳米粒子可增强电荷传导机制，这一点从掺杂样品明显改善的导电性结果中可见一斑。随着频率的增加，介电损耗（ε″）和介电常数（ε′）值降低。由于结构的变化以及光学、热学和介电性能的改善，所制备的样品（8 % MnFe2O4/CMC/PEO）是超级电容器和传感器等储能和光电应用的最佳选择。

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
