The recyclability of carbon nanotube (CNT) sponges in terms of oil absorption was studied. The sorption capacities of these sponges are greater than 100 g g(-1) for many organics and oils with viscosities of 3-200 cP, and they maintain sorption capacities of 20-40 g g(-1) after 10 cycles of absorption. About 98% of absorbed oil can be recovered by squeezing or converted to heat by directly burning the oil within the sponges. The sorption process has been described by a second-order kinetic model. The results demonstrate that CNT sponges are promising oil sorbents with good recyclability. (C) 2011 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
