摘要

Results: Adding a small amount of boron to carbon nanotubes helped bond them together to form a strong, three-dimensional network. The result was a resilient, ultralight sponge that could soak up more than 100 times its weight in oil and repel water. Why it matters: Scientists have had trouble bonding nanotubes together so that they can form large structures, but the new technique provides a way to do that. The first application could be making sorbents for cleaning up oil spills. Initial measurements suggest that the sponge can absorb more than three times as much oil or solvent as the best sorbents on the market but does not take up water, unlike some used now.
