Abstract

A supported nanofiber medium useful for segregating chemical species is provided by selecting a polymer, selecting a substrate; and electrospinning the polymer to form a nanofiber medium on the supporting substrate. When the substrate is a planar surface, the nanofiber medium will be a mat suitable for conducting chromatographic separation. When the substrate is a filament, the nanofiber medium is an annular mat suitable for solid phase microextraction. The nanofiber media formed may be selectively cross-linked and at least partially carbonized to carbon nanofibers. The nanofiber medium is supported on the substrate without the use of binder material.

Claims
