•WO3 electrochromic nanofibers were prepared by electrospinning technique.•WO3 nanofibers switched reversibly from transparent to blue color.•Electrochromic device was assembled using ionic liquid based gel electrolyte.•Significant optical modulation and excellent cycling stability were achieved for ECD.
The tungsten oxide (WO3) nanofibers were grown directly onto an ITO-coated glass via an electrospinning method for electrochromic applications. The electrochromic properties of WO3 nanofibers were investigated in the presence of different electrolytes including a series of ionic liquids and classic LiClO4-PC system. A significant optical modulation of 20.82% at 760 nm, reversible coloration with efficiency of 64.58 cm2/C and excellent cycling stability were achieved for the nanofiber electrochromic device (ECD) with ionic liquid based gel electrolyte.
