Green thermochromic materials are of great interest in many applications. Thermochromic and phase change materials are commonly used as smart devices to facilitate temperature sensing and passive heating/cooling systems, respectively. Since most of the current thermochromic materials are nondegradable, toxic, and/or nongreen, there is great opportunity to develop greener materials with high performance considering the wide range of materials that can exhibit thermochromism. This concise review distinguishes the different forms, phases, and chemical structures of thermochromic materials. A brief history of thermochromism is reviewed and a general distinction between reversible and irreversible thermochromism is provided. A general definition of green materials is provided, recent advances in the emerging field are critically discussed as well as future applications. This review also provides brief but thorough understanding of mechanistic pathways of this phenomenon in materials and the constituent requirements of green materials such that new systems can be designed using nontoxic, biobased, and/or biodegradable materials. Such green thermochromic materials will expand their use significantly.

绿色热致变色材料：简要回顾

绿色热致变色材料在许多应用中都引起了极大的兴趣。热致变色和相变材料通常用作智能设备，分别促进温度传感和被动加热/冷却系统。由于大多数当前的热致变色材料是不可降解的、有毒的和/或非绿色的，考虑到可以表现出热致变色的材料范围广泛，因此有很大的机会开发具有高性能的绿色材料。这篇简明的综述区分了热致变色材料的不同形式、相和化学结构。回顾了热致变色的简要历史，并提供了可逆和不可逆热致变色之间的一般区别。提供了绿色材料的一般定义，对新兴领域的最新进展以及未来的应用进行了批判性讨论。这篇综述还提供了对材料中这种现象的机理途径以及绿色材料的组成要求的简要而透彻的理解，以便可以使用无毒、生物基和/或可生物降解的材料设计新系统。这种绿色热致变色材料将显着扩大其用途。
