Abstract
Carbon nanofibrous (CNF) films are of great interest for various applications, e.g., as substrates for electrodes, sensors, or catalysts. Here, a fast microwave-assisted synthesis is reported to fabricate square-centimeter large free-standing carbon nanofibrous films of approximately 10 μm thickness utilizing nickel-based catalysts and ethanol as carbon source. The obtained CNF coatings exhibit a good stability and partial self-delamination from the substrate is observed, which enables their easy detachment from the substrate without the need for further treatment. Scanning electron microscopy is applied to investigate the morphology of the films and to develop a growth model. A fast microwave-assisted synthesis for the fabrication of square centimeter large free-standing carbon nanofibrous (CNF) films is reported. The obtained CNF coatings are about 10 μm thin and exhibit a good stability and partial self-delamination from the substrate, which enables their detachment from the substrate without the need for further treatment. Morphologic investigations by scanning electron microscopy and a growth model are presented. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
