Abstract

The phase behavior of the binary blends of polystyrene-b-poly(L-lactide) chiral block copolymer (BCP*) and polystyrene homopolymer (HS) is found to be strongly dependent on the molecular weight (Mn) of the HS. A helical phase is formed in the blends with low-Mn HS due to an enhancement of helical steric hindrance.
