Abstract
The design flexibility in crystalline structure and surface wettability makes the zeolitic imidazolate frameworks (ZIFs) excellent platform for task-specific applications. However, the key challenge lies in the precise modulation of transport channels, which still suffers from the slow diffusion kinetics in nanopores and the loss of hydrophobicity during long-term operation. Here we report a facile structural directing method to render the conventional three-dimensional polyhedrons to well controlled ZIF nanoplates, and further to super-hydrophobic laminated material by an in-situ phase transition strategy. As exemplified in water transport devices, the integrated ZIFs laminate shows exceptional anti-hydrolysis property and super-hydrophobic transport channels, which warrant the remarkable structural stability at fully wet conditions for a time length of at least three months, even under acidic condition and boiling water for 24 h. The simple transformation strategy paves the way for fabrication and regulation of coordinated structures where hydrophobic transport channels are required, and opens a new opportunity for smart design of advanced structures for water treatment under harsh environments.
