电子和能量存储和转换技术的进步带来了无数令人兴奋的材料设计挑战。含电荷嵌段聚合物（BP）提供了独特的功能，可以克服其中的一些挑战，因此在设计软材料领域引起了人们的极大兴趣。BP的性质与纳米结构组装体的动态和丰富的性质错综复杂地耦合，这是由嵌段之间的相分离引起的。在BPs中引入强大的二次力，如静电和氢键（H-键合），极大地影响了它们的自组装行为，因此通常以非平凡的方式影响它们的物理和电化学性质。在这篇综述中，一些流行的研究，这扩大了理解的结构-性能关系，包括几个设计策略，提高离子电导率和模量的带电嵌段聚合物，提出。静电和氢键的影响块聚合物热力学，这是最近的理论和实验工作证明的程度的深刻程度，也突出。从这里提出的研究中获得的见解有助于为先进软材料领域的长期和光明的未来奠定基础。
Advancements in electronics and energy storage and conversion technologies brings with it myriads of exciting material design challenges. Charge‐containing block polymers (BPs) offer unique features which can overcome some of these challenges and have thus aroused substantial interest within the field of designer soft materials. The properties of BPs are intricately coupled to the dynamic and rich nature of the nanostructured assemblies, which result from the phase separation between blocks. The introduction of strong secondary forces, such as electrostatics and hydrogen bonding (H‐bonding), into BPs greatly influences their self‐assembly behavior, and therefore affects their physical and electrochemical properties often in nontrivial ways. In this review, some of the prevailing research, which has expanded the understanding of structure–property relationships to include several design strategies for improving ionic conductivity and modulus in charged block polymers, is presented. The profound extent to which electrostatics and hydrogen bonding impact block polymer thermodynamics, an extent which is demonstrated by recent theoretical and experimental work, is also highlight. Insights gained from the research presented here help to lay the groundwork for a long and bright future in the field of advanced soft materials.
