Tunable Sizes and Aspect Ratios of Uniform Hexagonal/Rhombic Nanosheets with a Polyethylene Core via Crystallization-Driven Self-Assembly

Jianmin Wu, Boyang Shi, Ding Shen, Hanyu Lv et autres

Block copolymers (BCPs) are well-documented to undergo self-assembly into diverse nanostructures. Uniquely, BCPs with crystallizable core-forming blocks undergo crystallization-driven self-assembly (CDSA), typically yielding one-dimensional (1D) nanowires and two-dimensional (2D) nanosheets. However, the precise control over morphologies, sizes, and aspect ratios of 2D …
