THERMO-RESPONSIVE DUAL BAND ELECTROCHROMIC DEVICE
It relates to a thermo-responsive dual band electrochromic device, which is capable of selectively controlling the amount of sunlight radiation transmitted in the visible and in the near-infrared regions by operating under four distinct optical regimes, namely: fully transparent, visible blocking, near-infrared blocking, and fully blocking. The device can be regulated either by an electric stimulus, namely by controlling the sign and the intensity of the applied bias voltage, or by a thermal stimulus. In the latter the attenuation of incoming thermal radiation results increased as temperature increases. The thermo-responsive dual band electrochromic device comprises a first electrode consisting of a first transparent conductive substrate topped by a first electro-optically active layer and a second electrode consisting of a second transparent conductive substrate topped by a second electro-optically active layer separated by a temperature-dependent ion conductive layer consisting of a thermo-responsive polymer gel, an ion conductor and a plasticizer.

METHOD OF MANUFACTURING FLEXIBLE ELECTROCHROMIC DEVICE
The present disclosure relates to a method for manufacturing a flexible electrochromic device, and more particularly, to a method for manufacturing a flexible electrochromic device that bonds an electrochromic part and a counter electrode part while solidifying a wet-coated electrolyte with ultraviolet rays, thereby being capable of eliminating the possibility of bubble generation in the electrolyte and improving transmittance characteristics and durability.
NANOFIBER ASSEMBLIES WITH MULTIPLE ELECTROCHROMIC STATES
Composite assemblies are described that can be switched from a transparent state to a non transparent state, and in some examples even switched between different colors/reflectivities in the non transparent state. Switching between these states can be initiated by application of an electrical current to Ag carbon nanotube yarns in contact with an electrochromic electrolyte. The carbon nanotube yarns increase the efficiency with which electrons are provided to an electrolyte.
