An electro-optic window is provided, together with a method of manufacturing the window. The window (3) is made of a material substantially transparent to at least one of infra-red, visible and UV radiation and treated to have reduced RF/MI-CROWAVE transmission characteristics by the provision of a grid (1) set into at least one surface (2) thereof. The grid (1) is formed of a material selected to be either reflective or absorptive to RF/MICROWAVE radiation.

Provided are methods of forming graphene laminate compositions and architectures. The method comprises: (i) contacting a graphene structure comprising one or more planar graphene sheets with a first interlayer material; (ii) depositing of a conductive material, where in the conductive material is deposited along an edge of the graphene and one end of the first interlayer; and (iii) contacting the graphene structure with a second interlayer material. Also provided are graphene laminates structures comprising doped graphene films having improved mechanical strength, electrical mobility and optical transparency.

A ground structure-equipped laminated glass for vehicles is provided, with a countermeasure against static electricity on an electrically driven functional layer. The ground structure-equipped laminated glass for vehicles comprises a first glass plate, an interlayer and a second glass plate laminated in this order, wherein the interlayer has an electrically driven functional layer, a power supply member electrically connected to the electrically driven functional layer, a first circuit having the power supply member and the functional layer connected in series, and a second circuit having the power supply member, a flexible ESD shield, and a ground member connected in series, wherein at least one of the power supply member, the flexible ESD shield, and the ground member comprises a dielectric, and the ground member is grounded.
