具有可逆共价交联的聚合物网络构成了一类具有适应外部施加刺激的能力的新型材料。这些共价自适应网络（CAN）代表了聚合物网络制造的一种趋势，即合理设计具有特殊应用动态特性的结构材料。在这里，我们讨论了CAN的独特属性，必须考虑在设计，制造和表征这些智能材料，响应热或光化学刺激。虽然有许多可逆反应被认为是CAN中可能的交联候选物，但很少有容易且可重复可逆的反应。此外，由于其独特的属性，CAN的机械性能的表征需要特别考虑。最终，这些属性导致CAN显示出的有利特性，例如可回收性、可修复性、可调谐性、形状变化和低聚合应力。通过这一视角，我们确定了CAN新兴领域的几个趋势和未来方向，这些趋势和方向展示了迄今为止的进展以及进一步发展所需的基本要素。
Polymer networks possessing reversible covalent crosslinks constitute a novel material class with the capacity for adapting to an externally applied stimulus. These covalent adaptable networks (CANs) represent a trend in polymer network fabrication towards the rational design of structural materials possessing dynamic characteristics for specialty applications. Herein, we discuss the unique attributes of CANs that must be considered when designing, fabricating, and characterizing these smart materials that respond to either thermal or photochemical stimuli. While there are many reversible reactions which to consider as possible crosslink candidates in CANs, there are very few that are readily and repeatedly reversible. Furthermore, characterization of the mechanical properties of CANs requires special consideration owing to their unique attributes. Ultimately, these attributes are what lead to the advantageous properties displayed by CANs, such as recyclability, healability, tunability, shape changes, and low polymerization stress. Throughout this perspective, we identify several trends and future directions in the emerging field of CANs that demonstrate the progress to date as well as the essential elements that are needed for further advancement.
