AB  - A nanostructural polyaniline-poly(propylene oxide) (PANI-PPO) composite coating 
      was electrochemically synthesized on a stainless steel wire, by using acidic 
      ionic liquid 1-sulfobutyl-3-methylimidazolium hydrosulfate as supporting 
      electrolyte. The coating showed strong hydrophobicity and allowed for the direct 
      immersion solid-phase microextraction of carbamate pesticides (i.e. 
      2-(1-methylethoxy) phenyl methylcarbamate, m-tolyl-n-methylcarbamate, 
      2-(1-methylethyl) phenyl methylcarbamate, 2-(1-methylpropyl) phenol 
      methylcarbamate and 2,3-dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate) in 
      complex matrices. Moreover, this coating could be used for at least 120 times of 
      extraction. When it was coupled with gas chromatography for the determination of 
      these carbamate pesticides the linear ranges were about 0.1-100 mug L(-1) and the 
      detection limits were 0.012-0.048 mug L(-1). It also displayed acceptable 
      repeatability and reproducibility. When a fiber was used for five successive 
      measurements the relative standard deviations (RSDs) were smaller than 8.7%, and 
      the RSDs for fiber-to-fiber were 5.7-12.9% (n=5). The practical feasibility of 
      the proposed method was evaluated by determining carbamate pesticides in 
      vegetable samples and the recoveries for standards added were 79.8-108.8%.
