聚电解质（PEs）是沿链骨架携带可电离基团的聚合物，在生命和环境科学、工业应用和其他领域发挥着重要作用。由于PEs的复杂拓扑结构和静电相关性，PEs在体相和受限溶液中都表现出非常丰富的相行为和形态。

到目前为止，已经提出了许多理论、模拟和机器学习方法来研究聚电解质溶液的行为，特别是内在的结构-性质关系。

从个人的角度来看该方面，研究人员介绍了聚电解质溶液的几个最新趋势。该文考虑的主要主题是通过人工智能技术加速序列定义聚电解质（SDPE）的开发，本体SDPE溶液中的液液相分离，SDPE在单个介电表面附近的吸附行为，以及SDPE溶液介导的两个带电表面之间的表面力。

Abstract: Polyelectrolytes (PEs) are polymers carrying ionizable groups along the chain backbone and play an important role in life and environmental sciences, industrial applications and other fields. Due to the complicated topological structure and electrostatic correlations of PEs, PEs exhibit very rich phase behavior and morphologies in both bulk and confined solutions. So far, many theories, simulations and machine learning approaches have been proposed to study the behavior of polyelectrolyte solutions, especially the intrinsic structure-property relationships. In this perspective, from a personal point of view, we present several recent trends in polyelectrolyte solutions. The main themes considered here are accelerated development of sequence-defined polyelectrolyte (SDPE) via artificial intelligence technology, liquid-liquid phase separation in bulk SDPE solutions, adsorption behaviors of SDPE in the vicinity of a single dielectric surface, and surface forces between two charged surfaces mediated by SDPE solutions.
