Electrochromic Properties of Electrospun Fibers Based on Bis-Thiomethylcyclohexanone Derivatives

摘要

In this work, the electrochromic (EC) application of the hybrid fibers based on bis-thiomethylcyclohexanone derivatives is evaluated. For this purpose, two new bis-thiometh- ylcyclohexanone derivatives, 2,6-bis(phenyl(phenylthio)methyl) cyclohexanone (PPTMC) and 2,6-bis((2,6-dichlorophenyl)(phe- nylthio)methyl)cyclohexanone (CPPTMC), were synthesized by thio-Michael addition and characterized by spectroscopic methods and X-ray diffraction. The hybrid fibers based on bis- thiomethylcyclohexanone and poly(methyl methacrylate) (PMMA) were successfully prepared with electrospinning. The surface morphology and elemental compositions of these hybrid fibers were investigated by scanning electron micro- scopy (SEM) and energy dispersive X-ray spectroscopy (EDS). The electrochemical, optical and electrochromic behaviors of indium tin oxide (ITO) glass substrates coated with those fibers were evaluated using spectrophotometry techniques.
