Revolutionary Transparent Conductive Film
META is answering the need with NanoWeb®: The world’s highest-performance Indium-free transparent metal.
NanoWeb® is a transparent conductor made of an invisible metal mesh that can be fabricated onto any glass or plastic surface. It offers a superior alternative to Indium Tin Oxide (ITO), Silver Nanowire (AgNW), graphene and carbon nanotube among other ITO-alternative technologies.
It has a nanostructured thin metal layer that is a two-dimensional mesh of continuous wires. The design of the mesh geometry allows for a highly conductive and transparent layer. Due to its high conductivity, it is able to operate using very little power while remaining clear and transparent. Its grid of highly conductive lines allows more energy to pass through an open area surface versus unpatterned conductive materials.The metal mesh has been created from silver, aluminum, platinum, copper and nickel, but it can be done with almost any type of metals. The transparency depends only on geometrical design of the mesh and not the type of metal material. Sub-micron lines are designed to ensure there is no visibility to the human eye.
NanoWeb® has been developed using Rolling Mask Lithography (RML®). The RML process enables NanoWeb® to be produced for large products and devices, and films in roll-to-roll production.
