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.
Claims15
A method for manufacturing a supported nanofiber medium useful for segregating chemical species, comprising the steps of:
- selecting a polymer;
- selecting a substrate;
- and
- electrospinning the polymer, forming a nanofiber medium on the supporting substrate.
The method of one of the preceding claims, further comprising the step of:
- selectively cross-linking the nanofiber medium.
The method of one of the preceding claims, further comprising the step of:
- heating the nanofiber medium sufficiently to convert at least a portion of the nanofibers to carbon nanofibers.
The method of any one of the preceeding claims, wherein:
- the
- supported nanofiber medium is devoid of binder material.
A device for analytically separating chemical species, comprising:
- a substrate;
- a
- polymeric nanofiber medium formed on at least one surface of the substrate.
The device of one of claims 8 through 14, wherein:
- the
- supported nanofiber medium is devoid of binder material.
