Abstract
Certain example embodiments relate to electric, potentially-driven shades usable with insulating glass (IG) units, IG units including such shades, and/or associated methods. In such a unit, a dynamic shade is located between the substrates defining the IG unit, and is movable between retracted and extended positions. The dynamic shade includes on-glass layers including a transparent conductor and an insulator or dielectric film, as well as a shutter. The shutter includes a resilient polymer, a conductor, and optional ink. When the conductor is reflective, overcoat layers may be provided to help reduce internal reflection. The polymer may be capable of surviving high-temperature environments and may be colored in some instances. The polymer may be surface modified, e.g., to promote diffuse reflection, total internal reflection, etc.
