摘要：

Advanced flexible electronics have been attracting increasing attention nowadays. Herein, we fabricated an efficient flexible glucose sensor based on multi-walled carbon nanotubes coated carbonized silk fabric (MWCNTs/CSF) by Pt microsphere decoration. The MWCNTs/CSF was obtained by carbonization at 950 degrees C under an inert atmosphere, which showed good conductivity, flexibility and stability. After a decoration of Pt microspheres by electrodeposition, the resultant material showed a good sensitivity towards H2O2. Following with immobilizing with glucose oxidase (GOx), the resultant sensor showed a sensitivity of 288.86 mu A mM(-1) cm(-2) with a good linear range from 0 to 5 mM. This method is considered to be an efficient way to fabricate flexible electrodes and wearable electronic devices. (C) 2017 Elsevier B.V. All rights reserved.
