Functionalization-Induced Phase Separation Produces MWNTs/UHMWPE Microspheres with Size-Dependent Nanotube Localization

Functionalization-induced solubility collapse produces MWNTs/UHMWPE microspheres with size-dependent architectures. A bifunctional linker and a coupling agent trigger rapid phase segregation and MWNTs interfacial migration, yielding CNT-rich droplets. Larger droplets develop CNT-enriched shells, while smaller ones retain CNTs in their cores. SEM, TEM, and XRD confirm unique core-shell-corona structures.
