Several obstacles must be overcome, however, before CNTs live up to their expectations. Chief among these is the tendency of CNTs to clump together like strands of angel-hair pasta. Other challenges include a better understanding of CNT structures, and more effective ways of processing the tubes, sorting them, placing them on substrates, and engineering their properties.
Lehigh University, in collaboration with DuPont and MIT, recently received a four-year, $1.25-million grant from the National Science Foundation to solve these problems by developing and studying new methods of manipulating CNTs in solution.
