Effect of a conjugated/elastic block sequence on the morphology and electronic properties of polythiophene based stretchable block copolymers
We report the synthesis, morphology, and electronic properties of intrinsically stretchable AB-
type, ABA-type, and BAB-type block copolymers (BCPs) of poly (3-hexylthiophene)(P3HT: A
block) and elastic poly (octylene oxide)(POO: B block). By incorporating the soft coils, all
BCP thin films exhibited clear self-assembled fibrillary nanostructures and largely improved
stretchable mechanical properties within the films. The results from the absorption spectra
and AFM images indicated that the self-assembled structures of the P3HT blocks in the block …
