High-performance ferroelectric materials are widely used in various electronic devices owing to the function of mutual conversion among different energies, which mainly relates to their special structure gene of polarization configuration. Recent researches show that the high-entropy strategy has emerged as an effective and flexible approach for boosting physical properties in high-entropy ferroelectrics via the delicate design of local polarization configurations and other intrinsic effects caused by entropy increment, such as entropy stabilization, lattice disorder, inhibition of grain coarsening, improved mechanical properties, cocktail effect, and so on. In this review, the recent research progress about high-entropy ferroelectrics has been summarized, especially for the directional design of novel local polarization configurations according to the characteristics of different electrical properties such as high piezoelectricity, high-efficiency energy storage, and large electrostriction, providing a guidance for designing and exploring more novel local polarization configurations in high-entropy ferroelectrics for generating higher performance.

通过高熵策略的高性能铁电基材料：设计、性能和机制

高性能铁电材料由于具有不同能量之间相互转换的功能而广泛应用于各种电子器件中，这主要与其极化构型的特殊结构基因有关。最近的研究表明，高熵策略已成为一种有效且灵活的方法，通过局部极化构型的精细设计以及熵增量引起的其他内在效应（例如熵稳定、晶格无序）来提高高熵铁电体的物理性能、抑制晶粒粗化、改善力学性能、鸡尾酒效应等。本文综述了近年来高熵铁电体的研究进展，特别是针对不同电学特性如高压电、高效储能、大电致伸缩等特点，定向设计新型局域极化构型，为设计和探索高熵铁电体中更新颖的局部极化配置提供指导，以产生更高的性能。
