Abstract：
We synthesized high-heat-resistant adhesives based on metal - organic frameworks owing to their high decomposition temperature and the absence of a glass transition. Heat-resistance tests were performed on adhesive joints consisting of zeolitic imidazolate framework (ZIF)-67-based adhesives and a copper substrate. The as-synthesized ZIF-67-based adhesive exhibited heat resistances at 600 and 700°C in air and nitrogen atmospheres, respectively, comparable to those of conventional high-heat-resistant polymer-based adhesives. The degradation mechanism of the ZIF-67 adhesives was investigated, and their high heat resistance was attributed to the stable existence of the ZIF-67 qtz phase in the adhesive layer at high temperatures without the formation of voids. Thus, adhesives based on ZIF-67 and other metal - organic frameworks can be applied in high-temperature industrial systems.
By focusing on its high thermal stability and absence of glass transition, the ZIF-67 gel was found to have high potential that is comparable to existing heat-resistant adhesives.

摘要：
我们合成了基于金属-有机骨架的高耐热粘合剂，因为它们的分解温度高且没有玻璃化转变。对由基于沸石咪唑酯骨架（ZIF）-67的粘合剂和铜基材组成的粘合剂接头进行了耐热性测试。合成的ZIF-67基粘合剂在空气和氮气气氛中在600和700°C下表现出耐热性，分别,与传统的高耐热聚合物基粘合剂相当。研究了ZIF-67胶粘剂的降解机理,它们的高耐热性归因于ZIF-67qtz相在高温下在粘合剂层中的稳定存在而没有形成空隙。因此，基于ZIF-67和其他金属有机框架的粘合剂可应用于高温工业系统。
通过关注其高热稳定性和不存在玻璃化转变，发现ZIF-67凝胶具有与现有耐热粘合剂相当的高潜力。
