摘要

A poly(3-methylthiophene-carbazole)/graphene oxide composite coating was prepared on a stainless steel wire through electrochemical method. It showed high extraction efficiency, thermal stability and durability than those of corresponding single-component coatings due to the synergistic effect of different components. The resulting fiber was used for the headspace solid phase microextraction of octanal, nonanal, decanal, undecanol and dodecanol, followed by gas chromatography detection. The results showed that their GC peak areas were linear to their concentrations in the ranges of about 0.05-100μgL
