Peeling off nanotubes : Chemically modified soft polydimethylsiloxane (PDMS) thin films act as “scotch tape” for the separation of semiconducting (s) and metallic (m) single‐walled carbon nanotubes (SWNTs). Whereas the amine‐functionalized A‐scotch tape selectively removed s‐SWNTs, the phenyl‐functionalized P‐scotch tape acted specifically towards m‐SWNTs (see picture). The resulting separation process is very gentle, no damage to the SWNTs was observed.
