Abstract

Abstract Microstructural analysis is an important technique to study the extent of interaction between metal fillers and polymers. The aim of this study is to review the investigations on the microstructural properties of metal-reinforced polymer composites. Scanning Electron Microscope (SEM) operating at a magnification range of 2,500× is typically used for examining the microstructure of the composites. Microstructural analysis reveals two key qualitative informations, dispersion and interfacial adhesion. It was observed from the review that flaky metal fillers will maximise dispersion and interfacial adhesion hence leading to improved mechanical, tribological, electrical, and thermal properties of the composites. Utilizing ternary metallic components helps to eliminate aggregation because the cohesion of metal particles is limited. It is important that future microstructural studies evaluate nano-sized fillers as compared to micro-sized ones. Also, it is important to quantitatively correlate the arrangement of the fillers to macro-scale properties and finite element analysis is an important tool that can help achieving this.

探测金属增强聚合物复合材料的微观结构特性

摘要微结构分析是研究金属填料与聚合物之间相互作用程度的一项重要技术。本研究旨在回顾对金属增强聚合物复合材料微观结构特性的研究。通常使用放大倍数为 2,500 倍的扫描电子显微镜（SEM）来检查复合材料的微观结构。微观结构分析揭示了两个关键的定性信息：分散性和界面粘附性。研究发现，片状金属填料可最大限度地提高分散性和界面粘附性，从而改善复合材料的机械、摩擦、电气和热性能。由于金属颗粒的内聚力有限，因此使用三元金属成分有助于消除聚集现象。重要的是，未来的微结构研究应将纳米级填料与微米级填料进行比较评估。此外，将填料的排列与宏观性能进行定量关联也很重要，而有限元分析是有助于实现这一目标的重要工具。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
