聚合物衍生陶瓷（PDC）纳米复合材料可以从分子设计到加入纳米填料，获得大量的功能特性库。调整预陶瓷聚合物（PCP）的化学性质和纳米填料的尺寸和形态，可以使纳米复合材料用于复杂形状和具有增强的热性能和机械性能的涂层。目标纳米复合材料的合理设计需要理解基本的结构-性能-性能关系。因此，我们将PCP设计和纳米填料集成的讨论调整为单源前体以及功能化PDCs的热解处理。我们还讨论了先进表征技术的前景和局限性，如4D透射电子显微镜和对分布函数，以实现原位映射结构演化。现场监测的反馈回路为人工智能加速材料发现奠定了基础。本展望评估了PDC纳米复合材料的最新研究进展，并提出了PDC纳米复合材料的合成、制造、加工和高级表征方面的科学和工程挑战，以增强其磁、电、能量转换和存储性能。
Polymer-derived ceramic (PDC) nanocomposites enable access to a large library of functional properties starting from molecular design and incorporating nanofillers. Tailoring preceramic polymer (PCP) chemistry and nanofiller size and morphology can lead to usage of the nanocomposites in complex shapes and coatings with enhanced thermal and mechanical properties. A rational design of targeted nanocomposites requires an understanding of fundamental structure–property–performance relations. Thus, we tailor our discussions of PCP design and nanofiller integration into single source precursors as well as pyrolytic processing for functionalizing PDCs. We also discuss the promises and limitations of advanced characterization techniques such as 4D transmission electron microscopy and pair distribution functions to enable in situ mapping structural evolution. The feedback loop of in situ monitoring sets the foundation for enabling accelerated materials discovery with artificial intelligence. This perspective assesses the recent progress of PDC nanocomposite research nanocomposites and presents scientific and engineering challenges for synthesis, fabrication, processing, and advanced characterization of PDC nanocomposites for enhanced magnetic, electrical, and energy conversion and storage properties.
