Abstract[English]
The present invention provides a facile heteroepitaxial method for growing conductive zinc-catecholate frameworks on bio-fibers with biomimetic connections, which is beneficial to fabricate biocompatible and high-performance photodetectors and chemiresistors, and the corresponding bio-fiber based metal-organic framework. In this method, a conductive layer is first introduced on the surface of polysaccharide bio-fibers, before well-aligned zinc oxide nanoarrays were densely constructed on the bio-fibers by a physiological coagulation mechanism. The obtained fibrous materials may be used in devices, including in electronic components, having the advantages of good stability, environmental-friendly, flame retardancy, and high response.[French]
La présente invention concerne un procédé hétéroépitaxial facile pour faire croître des structures conductrices de zinc-catécholate sur des biofibres avec des connexions biomimétiques, ce qui est avantageux pour la fabrication de photodétecteurs et de chimiorésistances biocompatibles et à haute performance, et la structure métallo-organique correspondante à base de biofibres. Dans ce procédé, une couche conductrice est d'abord introduite à la surface de biofibres de polysaccharide, avant que des nanoréseaux d'oxyde de zinc bien alignés ne soient densément construits sur les biofibres par un mécanisme de coagulation physiologique. Les matériaux fibreux obtenus peuvent être utilisés dans des dispositifs, y compris dans des composants électroniques, présentant les avantages suivants : bonne stabilité, respect de l'environnement, caractère ignifugeant et réponse élevée.
