Paper Abstract

This paper discusses the design, fabrication and characterization of lens for smart sunglasses based on electrochromic devices. The prepared electrochromic device was fabricated with ITO coated PET plastic. The working EC material film was poly [3,3-dimethyl-3,4-dihydro-2H-thieno [3,4-b][1,4]dioxepine] (PProDOT-Me2), while the counter layer of the device was vanadium oxide titanium oxide (V2O5/TiO2) composite film, which serves as an ion storage layer. A solution type electrolyte as the ionic transport layer was sandwiched between the working and counter layers. The lens exhibited tuneable shade in visible light wave length, with a maximum contrast ratio at 580nm.
