Nanomaterials have become an established area of academic research and have gained commercial importance due to their valuable physicochemical properties, such as large surface area, high mechanical strength as well as unique optical and electrical features. Numerous nanosize architectures have been researched and reported to date including quantum dots, fullerenes, nanorods, nanowires, nanofibers, nanosheets, nanowalls, nanocoils, and nanoballs, etc. Among these materials, nanofibers are extremely valuable morphologies used across many industries spanning from textile to medical applications and beyond. This review article focuses on the various works and reports of MgO-based applications and its overlap with nanofiber-based structures. Comprehensive review of the growing number of reports to date provides a unified resource for researchers going forward. As the acceptance and broader set of applications continues its exponential growth in commercial and academic output, it is envisaged that MgO-based composites will play a central part in many future reports of nanofibrous composites and other composite architectures, e.g., particle-reinforced composites, metal matrix composites, ceramic matrix composites, etc., due to the wide variety of applications to which MgO is suited, as well as other peripheral properties such as cost, availability, ease-of-handling, and use, etc. Indeed, despite the many preliminary reports to date, there remains a great deal yet to discover and optimize for such systems.

纳米材料由于其宝贵的物理化学特性，例如大的表面积，高的机械强度以及独特的光学和电学特性，已经成为学术研究的公认领域，并已获得商业重要性。迄今为止，已经研究并报道了许多纳米尺寸的体系结构，包括量子点，富勒烯，纳米棒，纳米线，纳米纤维，纳米片，纳米壁，纳米线圈和纳米球等。在这些材料中，纳米纤维是非常有价值的形貌，在从纺织到纺织，医疗应用及其他。本文将重点介绍基于MgO的应用的各种工作和报告，以及其与基于纳米纤维的结构的重叠。迄今为止，对不断增长的报告数量进行全面审查为研究人员提供了统一的资源。随着商业应用和学术产品的接受和广泛应用的持续增长，人们预计基于MgO的复合材料将在许多未来的纳米纤维复合材料和其他复合材料结构（例如颗粒增强复合材料）的报告中发挥核心作用，金属基复合材料，陶瓷基复合材料等，这是因为MgO适用于多种应用，以及其他外围特性，例如成本，可用性，易操作性和使用性等。迄今为止的许多初步报告中，仍然有很多要针对此类系统进行发现和优化。
