The mesoscale assembly process is sensitive to additives that can modify the interactions of the crystal nucleus and the developing crystals with solid surfaces and soluble molecules. However, the presence of additives is not a prerequisite for the mesoscale transformation process. In this study, ZnO sheet networks were synthesized on Al foils by a hydrothermal process. Scanning electron microscopy and transmission electron microscopy images confirmed that under ultrasonic vibration, monolithic polycrystalline ZnO sheets transformed into hexagon-like mesocrystalline tubes or rods. The formation mechanism was discussed.
介观组装过程对添加剂敏感，添加剂可以改变晶核和正在生长的晶体与固体表面和可溶性分子的相互作用。然而，添加剂的存在并不是介观转变过程的必要条件。在这项研究中，通过水热法在铝箔上合成了氧化锌片层网络。扫描电子显微镜和透射电子显微镜图像证实，在超声振动下，单晶多晶氧化锌片层转变成了六方介观管状或棒状结构。讨论了其形成机制。
