摘要：

Microtubes made of multi-walled carbon nanotubes were prepared via infiltration of CNT-suspension through a microfiltration hollow fiber membrane. Shrinking of the entangled CNT network during the drying allows withdrawal of CNT-microtubes from the hollow fiber. Currently, microtubes have a length of similar to 50 cm, outer diameter of similar to 1.7 mm and scalable inner diameter by varying the infiltration time resulting in wall thicknesses of 130-320 mu m. The BET surface area is 200 m(2)/g with a porosity of 48-67% and an electrical conductivity similar to 20 S/cm. We propose to use such novel CNT-microtubes for the fabrication of tubular electrochemical cells and membrane filtration processes. (C) 2013 Elsevier Ltd. All rights reserved.
