超临界流体是一种在材料工程中使用的高度通用的溶剂，并且可以用于开发用于合成和制造功能材料的可持续和绿色工艺。特别是，超临界CO2（scCO2）可用于减少能源和材料消耗，降低受试者的材料强度。超临界CO2的成功应用的关键是开发其良好的传热和传质性能。利用超临界二氧化碳的传质特性（粘度降低和扩散性）在材料工程中的应用已在文献中得到广泛证实。材料工程系统的开发需要对工艺前后的能源和溶剂消耗进行严格分析，以实现新材料的可持续生产。预计超临界CO2将在材料工程中发挥重要作用，并预计将开发新的协议，方法和应用。
A supercritical fluid is a highly versatile solvent used in materials engineering and could be utilized to develop sustainable and green processes for synthesizing and manufacturing functional materials. In particular, supercritical CO 2 (scCO 2) can be used to reduce energy and material consumption, lowering the material intensity of the subject. The key to the successful application of scCO 2 is the exploitation of its favorable properties for both heat and mass transfer. Applications in materials engineering that take advantage of the mass-transfer properties of scCO 2 (viscosity reduction and diffusivity) have been widely demonstrated in the literature. The development of materials engineering systems will require critical analysis of both pre-and post-process energy and solvent consumption to achieve sustainable production of new materials. It is expected that scCO 2 will play an important role in materials engineering, and the development of new protocols, methodologies, and applications are anticipated.
