Using the liquid metal dealloying process, a hetero-structured composite with a 3D interconnected structure, which is the target stage of the task, was developed and its excellent properties were successfully proved.Due to the disordered and unique structure, load transfer and strain partitioning between the commponent phases effectively occurred, thereby ensuring excellent mechanical properties.In the case of photoelectrodes to be developed by future research, it can be judged that they will have excellent durability based on these excellent mechanical properties.I think I laid the foundation stone as a basic study for the leap into the future of element.

利用液态金属合金化工艺，开发了具有三维互联结构的异质结构复合材料，并成功地证明了其优异的性能。由于结构的无序性和独特性，构件相之间有效地进行了载荷传递和应变分配，从而保证了优异的力学性能。以未来研究开发的光电极为例，基于这些优异的力学性能，可以判断其具有优异的耐久性。我认为我作为基础学习为跨入元素的未来打下了基石。
