An insulating glass unit, comprising: first and second substrates, each having interior and exterior major surfaces, the interior major surface of the first substrate facing the interior major surface of the second substrate; a spacer system for helping to maintain the first and second substrates in substantially parallel spaced apart relation to one another and to define a gap therebetween; and a dynamically controllable shade (202a, 202b) interposed between the first and second substrates, the shade (202a, 202b) including: a first conductive coating provided, directly or indirectly, on the interior major surface of the first substrate; a dielectric or insulator film provided, directly or indirectly, on the first conductive coating; and a shutter including a polymer material supporting a second conductive coating, the polymer material being extendible to serve as a shutter closed position and retractable to serve a shutter open position; wherein the first and second conductive coatings are configured to be electrically connectable to a power source that is controllable to selectively set up an electric potential difference to correspondingly drive the polymer material between the shutter open and closed positions; and characterized in that the second conductive coating includes a thin film layer comprising Mo and/or Ti; and wherein a corrosion-reducing layer is provided over the thin film layer comprising Mo and/or Ti and on a surface thereof opposite the polymer material. first and second substrates, each having interior and exterior major surfaces, the interior major surface of the first substrate facing the interior major surface of the second substrate; a spacer system for helping to maintain the first and second substrates in substantially parallel spaced apart relation to one another and to define a gap therebetween; and a dynamically controllable shade (202a, 202b) interposed between the first and second substrates, the shade (202a, 202b) including: a first conductive coating provided, directly or indirectly, on the interior major surface of the first substrate; a dielectric or insulator film provided, directly or indirectly, on the first conductive coating; and a shutter including a polymer material supporting a second conductive coating, the polymer material being extendible to serve as a shutter closed position and retractable to serve a shutter open position; a first conductive coating provided, directly or indirectly, on the interior major surface of the first substrate; a dielectric or insulator film provided, directly or indirectly, on the first conductive coating; and a shutter including a polymer material supporting a second conductive coating, the polymer material being extendible to serve as a shutter closed position and retractable to serve a shutter open position; wherein the first and second conductive coatings are configured to be electrically connectable to a power source that is controllable to selectively set up an electric potential difference to correspondingly drive the polymer material between the shutter open and closed positions; and characterized in that the second conductive coating includes a thin film layer comprising Mo and/or Ti; and wherein a corrosion-reducing layer is provided over the thin film layer comprising Mo and/or Ti and on a surface thereof opposite the polymer material.
