Fecha de publicación: | 2018 | Editor: | Wiley-VCH | Citación: | Angewandte Chemie International Edition 57(47): 15420-15424 (2018) | Resumen: | Herein, we exploit the well-known swelling behaviour of metal-organic frameworks (MOFs) to create a self-folding polymer film. Namely, we show that incorporating crystals of the flexible MOF MIL-88A into a polyvinylidene difluoride (PVDF) matrix affords a polymer composite film that undergoes reversible shape transformations upon exposure to polar solvents and vapours. Since the self-folding properties of this film correlate directly with the swelling properties of the MIL-88A crystals, it selectively bends to certain solvents and its degree of folding can be controlled by controlling the relative humidity. Moreover, it shows a shape-memory effect at relative humidity values from 60 % to 90 %. As proof of concept, we demonstrate that these composite films can lift cargo and can be used to assemble 3D structures from 2D patterns. Our strategy is a straightforward method for designing autonomous soft materials with folding properties that can be tuned by judicious choice of the constituent flexible MOF. | Versión del editor: | https://doi.org/10.1002/anie.201808433 | URI: | http://hdl.handle.net/10261/199042 | DOI: | 10.1002/anie.201808433 | ISSN: | 1433-7851 | E-ISSN: | 1521-3773 |
