METHOD FOR COVERING A SPME FIBRE WITH CARBON NANOTUBES AND RESULTING SPME FIBRE

摘要

The invention relates to a method for covering solid phase microextraction (SPME) fibres with carbon nanotubes (CNT), comprising the following operations: (i) depositing a layer of a metal material on the SPME fibre; (ii) applying a heat treatment in order to form catalytic metal nanoparticles in a reducing atmosphere; and (iii) applying carbon using chemical deposition techniques, thereby forming CNT on top of the metal nanoparticles. The invention also relates to a fibre obtained using this method.
