    摘要: Monolithic, macroscopic, nanoporous nanotube filters are fabricated having radially aligned carbon nanotube walls. The freestanding filters have diameters and lengths up to several centimeters. A single-step filtering process was demonstrated in two important settings: the elimination of multiple components of heavy hydrocarbons from petroleum, a crucial step in post-distillation of crude oil, and the elimination of bacterial contaminants such as Escherichia coli or the nanometer-sized poliovirus from drinking water. All the filtration processes were repeated several times with completely reproducible results. These nanotube filters can be cleaned repeatedly after each filtration process to regain their full filtering efficiency.
