Formvar/Carbon support films consist of a thin layer of Carbon evaporated onto a Formvar film. This offers improved conductive properties in comparison to standard Formvar films. These are typically thicker support films which may compromise high resolution imaging but will return a stronger and more stable film. The Formvar layer is typically approx.10nm thick with a thin (<5nm) layer of Carbon on top. Different combinations of grid meshes, pack sizes and film thicknesses are available on request.
