Self-Assembly of Conjugated Block-Copolymers and Nanoparticles

The ability to control the molecular packing and nanoscale morphology of conjugated polymers is important for many of their applications. Here, we present the fabrication of well-ordered nanowire arrays of conjugated polymers and nanoparticles based on the binary self-assembly of a conjugated block-copolymer, poly(3-hexylthiophene)-block-poly(ethylene glycol) (P3HT-b-PEG) and nanoparticles at the air-liquid interface. The presentation will discuss how the binary self-assembly differs from that of prototypical coil-coil type block copolymers and present how we utilize the polymer films for the fabrication of responsive thin film interference colors.
