AB  - The present work reports the electrochemical fabrication of an ionic liquid 
      functionalized multiwalled carbon nanotubes-polyaniline (MWCNT@IL/PANI) 
      nanocomposite coating and its application in the headspace-solid phase 
      microextraction (HS-SPME) and gas chromatography (GC) determination of benzoic 
      acid esters (i.e., methyl benzoate, ethyl benzoate, propyl benzoate and butyl 
      benzoate). The MWCNTs was firstly functionalized with amine-terminated IL 
      (MWCNT@IL) through chemical reduction, and then was doped in PANI during the 
      electropolymerization of aniline. The resulting coating was characterized by 
      infrared spectroscopy, field emission scanning electron microscopy and thermo 
      gravimetry. It showed net-like structure and had high thermal stability (up to 
      330 degrees C). Furthermore, it presented high selectivity for the four benzoic acid 
      esters and thus suited for their HS-SPME-GC determination. Results showed that 
      under optimized extraction conditions, the detection limits were less than 
      6.1ngL(-1) (S/N=3) and the linear detection ranges were 0.012-50mugL(-1) 
      (R>/=0.9957) for these analytes. The relative standard deviations (RSDs) were lower 
      than 6.4% for five successive measurements with one fiber, and the RSDs for 
      fiber-to-fiber were 4.4-9.6% (n=5). The developed method was successfully applied 
      to the determination of these benzoic acid esters in perfume samples.
