Constructing Cylindrical Nanostructures Via Directional Morphology Evolution Induced by Seeded Polymerization

Macromol Rapid Commun. 2021 May;42(9):e2100001. doi: 10.1002/marc.202100001. Epub 2021 Feb 5.

Abstract

Herein, spindle-shaped block copolymer (BCP) nanoparticles are used in seeded polymerization of methyl methacrylate as a novel approach to generating cylindrical nanostructures. The chain-extension of BCP seeds by an amorphous coil-type polymer within the seed core composed of semifluorinated liquid-crystalline blocks triggers the deforming, stretching, and directional growth of the seeds along the long axis, eventually leads to nanorods.

Keywords: cylindrical nanostructures; directional morphology evolution; liquid-crystalline ordering; polymerization-induced self-assembly; seeded polymerization; spindle-shaped nanoparticles.
