Mechanical alignment of quasi-one-dimensional nanoparticles.
Randomly oriented rod or rope-like nanoparticles on the surface of an elastomeric substrate are aligned along one direction simply by stretching the substrate. The technique is demonstrated here using single-walled carbon nanotube ropes, and the degree of alignment is assessed by polarized Raman spectroscopy. The alignment is preserved after the particles are removed from the substrate surface, showing that the aligned nanoparticles can be stamped in patterns onto another surface.
