摘要：

Herein, we fabricated MWCNT-OH adsorbed electrospun nylon 6,6 nanofibers by electrospinning and dip coating method. The amount of MWCNT-OH adsorbed to the pure electrospun nylon 6,6 nanofibers was 0.056 Mt. The electrical conductivity of MWCNT-OH adsorbed electrospun nylon 6,6 nanofibers was 5.24 x 10(-3) S cm(-1). We also investigated the sensing properties of MWCNT-OH adsorbed electrospun nylon 6,6 nanofibers by measuring its response upon exposure to low molecular weight alcohol vapours such as methanol, ethanol, 1-propanol, and 1-butanol. The changes of the electrical resistance of MWCNT-OH adsorbed electrospun nylon 6,6 nanofibers were demonstrated on the basis of hydrogen bonds among the alcohol vapours and hydroxyl groups (-OH) on MWCNT-OH, and amide groups (-NHCO-) in nylon 6,6. The fabricated sensor showed good reversible and reproducible responses upon the cyclic test. (C) 2010 Elsevier B.V. All rights reserved.
