摘要： 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.
