摘要

随着现代科学技术的蓬勃发展,电介质复合材料在电子、储能、传感器等众多领域的应用需求正在不断增加,特别是在电容器等能源储存以及传感技术方面,其介电性能更是发挥着至关重要的作用。传统烧结技术在制备陶瓷材料时,通常需要高温处理,这样不仅能耗高,还可能导致材料的相变和晶粒过度生长。为了解决这些问题,冷压烧结技术应运而生。冷压烧结技术作为一种新兴的超低温烧结方法,不仅能够显著提升电介质复合材料的介电性能,还能保持高分子材料的柔韧性以及其他优良特性,这使得此类型复合材料在多种应用中展现出巨大的潜力。本文系统阐述了冷压烧结的基本原理,重点分析了其在低温下优化电介质复合材料时的介电性能机理,并且探讨了冷压烧结工艺如何改善复合材料的介电常数、击穿强度及热稳定性等重要性能。探讨了冷压烧结工艺在提升电介质复合材料介电性能方面的最新研究进展。最后,分析了冷压烧结工艺面临的挑战,并对其实际应用前景进行了展望。

Abstract

With the burgeoning advancement of modern technology, the demand for dielectric composites in electronics, energy storage, sensors, and other fields continues to rise. Their dielectric properties play a critical role, particularly in energy storage applications such as capacitors and sensing technologies. Traditional sintering techniques for fabricating ceramic materials typically require high-temperature processing, which not only consumes significant energy but may also induces detrimental phase transformation and excessive grain growth. To address these challenges, cold pressing sintering has emerged as a novel ultra-low-temperature processing method. This approach not only significantly enhances the dielectric property of composites but also preserves the flexibility and other advantageous properties of polymer matrices, thereby demonstrating substantial potential for diverse applications. In this review, the work systematically elucidates the fundamental principles of cold pressing sintering, with a focus on its mechanisms for optimizing dielectric properties (e.g., dielectric constant, breakdown strength, and thermal stability) at low temperature. It further examines recent advances in cold pressing sintering for enhancing dielectric properties and discusses the current challenges and future prospects for practical implementation.
