AB  - A novel multiwalled carbon nanotubes-polyaniline composite (MWCNTs-PANI) film 
      coated platinum wire was fabricated through electrochemical deposition. The 
      coating was characterized by scanning electron microscopy (SEM), Fourier 
      transform infrared (FTIR) spectrophotometry and thermogravimetry. It was found 
      that the coating was porous and had large specific area and adsorption capacity; 
      in the composite MWCNTs and polyaniline interacted with each other and the film 
      kept stable up to 320 degrees C. The as-made fiber was used for the headspace 
      solid-phase microextraction (HS-SPME) of some phenolic compounds (i.e. 
      2-chlorophenol, 2,4-dichlorophenol, 2-methylphenol, 3-methylphenol, 
      2,6-dimethylphenol, 2-nitrophenol), followed by gas chromatographic analysis. The 
      MWCNTs-PANI coating showed better analytical performance than PANI. Under the 
      optimized conditions, the detection limits were 1.89-65.9 ng L(-1), the relative 
      standard deviations (RSDs) were 2.7-6.5% for six successive measurements with 
      single fiber, the RSDs for fiber-to-fiber were 5.2-12.4%, the linear ranges 
      exceeded two magnitudes with correlation coefficient above 0.992. The fiber could 
      be used for more than 250 times without decrease of efficiency. The proposed 
      method was successfully applied to the extraction and determination of phenolic 
      compounds in water sample, and the recoveries were 87.7-111.5% for different 
      analytes. In addition, the fiber also presented advantages of easy preparation 
      and low cost. Therefore, it is a promising SPME fiber.
