Mesocrystal, composed of same-oriented nanocrystals separated by organics, is a promising structure for superior chem. and mech. properties, in which the high d. of nanocrystal-organic interfaces plays a crucial role. The stability of the interfaces determines the service temperature and strength of the material. Here, we synthesized aluminum mesocrystal using electrodeposition in ionic liquids with Me nicotinate additive and investigated its thermal and mech. stability. In contrast to the low stability of nanograined metals and nanoporous metals with comparable grain sizes, the Al mesocrystal is found to be stable up to 320°C (0.63 Tm, Tm: the m.p.) and has a recorded high hardness of 2.27 GPa. The high stability originates from the suppression of migration and free diffusion of the interfaces.
