Carbon Nanotubes: High-Temperature Operating Non-volatile Memory of Printable Single-Wall Carbon Nanotubes Self-Assembled with a Conjugate Block Copolymer (Small 6/2013)

C. Park and co-workers develop high-performance, printable, non-volatile polymer memories with solution-processed nanocomposite films of a conjugated block copolymer, poly(styrene-block-paraphenylene) (PS-b-PPP), and single-walled carbon nanotubes (SWNTs). The devices, described on page 831, show excellent reliability of both data retention over time and read/write cycle endurance at high temperatures of up to 100 °C without significant performance degradation. This arises from the strong, non-destructive, and isomorphic π–π interactions between the SWNTs and the PPP block.
