✦ Synopsis

Abstract

Summary: Tetraaniline‐block‐poly(L‐lactide) diblock oligomers are synthesized via ring‐opening polymerization. The diblock oligomers cast from an L‐lactide selective solvent (chloroform) show spherical aggregates for the leucoemeraldine state, and ring‐like structures that are composed of much smaller spherical aggregates for the emeraldine state. The formation mechanisms of the two different surface morphologies are discussed in detail.

Surface morphology changes induced by oxidation of the aniline segment of tetraaniline‐block‐poly(L‐lactate) and drying effects.
