Single-Walled Carbon Nanotube-Induced Orthogonal Growth of Polyethylene Single Crystals at a Curved Liquid/Liquid Interface

Abstract

We report herein single-walled carbon nanotube-induced polyethylene crystallization at the curved liquid/liquid interface. A Pickering emulsion system comprised of polyethylene (PE)/single-walled carbon nanotubes (SWCNTs)/1,2-dichlorobenzene (DCB)/water is formed using probe sonication at an elevated temperature. SWCNTs are used as the Pickering agents, and they are bent into nanosized rings by the curved DCB/water interface. Upon cooling, PE crystallizes onto SWCNTs, forming kebab single crystals, and the PE lamellae are orthogonal to the DCB/water interface. The unique structure resembles nanohybrid shish kebab (NHSK) rings
