Amphiphobic Carbon Nanotubes as Macroemulsion Surfactants

Abstract
Single-walled carbon nanotubes (SWNTs) are insoluble in either water or oil. When mixtures of SWNTs, water, and toluene are sheared rigorously, a macroscopic emulsion ofwater droplets form in toluene with SWNTs residing at interfaces between water and toluene, acting as a natural surfactant or interphase material. The average droplet dimension decreases as SWNT/water mass ratio increases, implying a coarsening-pinning mechanism. The concept of emulsification via amphiphobicity will find applications in processing nanotubes, compatibiliizing immiscible fluids, and creating new macroscopic emulsion materials with unique interfacial and structural properties.Citation
