Herein, it has been developed a method to prepare metallic foams starting from Zamak5 (ZnAlCu alloy) with different pore sizes. The Zamak5 metallic foam is designed to serve as a support and metallic precursor of ZIF-8. In this way, composite materials MOF-metal can be prepared, these composites have a large number of application in energy exchange processe such as: adsorption or chemical reactions. Additionally, this method of sythesizing MOFs is environmentally friendly thanks to absence of solvents. Hanerssing the low melting point of the linker, the linker is infiltrated into the foam where the foam and the linker react to form the ZIF-8. In this way we have managed to transform part of the foam into ZIF-8 crystals that remain adhered to the foam. The foams have been characterized and modeled studying the mechanical and electrical properties, finding that both can be predected by various models. Among these, Ashby and Mortensen models for mechanical properties and Ashby and Percolation model for electrical properties stand.
在此，已开发出一种从不同孔径的 Zamak5（锌铝合金铜合金）制备金属泡沫的方法。Zamak5 金属泡沫被设计用作 ZIF-8 的支撑体和金属前驱体。通过这种方式，可以制备 MOF-金属复合材料，这些复合材料在能量交换过程中有大量应用，例如：吸附或化学反应。此外，由于无需溶剂，这种合成 MOF 的方法对环境友好。利用连接体的低熔点，将连接体渗入泡沫中，在那里泡沫与连接体反应形成 ZIF-8。通过这种方式，我们成功地将部分泡沫转化为仍附着在泡沫上的 ZIF-8 晶体。对泡沫进行了表征和建模，研究了其力学和电学性能，发现两者都可以通过各种模型进行预测。其中，用于力学性能的阿什比（Ashby）和莫特森（Mortensen）模型以及用于电学性能的阿什比和渗流模型较为突出。
