Scratch testing of nanofilms for flexible electronics
11 Jul 2023Metallic nanofilms on polymer substrates are used for a variety of applications in flexible electronics. To ensure the reliability of such flexible electronic devices, the scratch adhesion property of the nanofilm is evaluated for the critical normal load as a part of R&D and QC activities. This application note explores the capabilities of Bruker’s scratch test system and includes an example of its evaluation of a metallic nanofilm on a polymer substrate.

NanotechnologyNanotechnology, or nanotech, is an engineering technique using molecular scale functional systems. Applications of nanotechnology include medicine and medical devices, electronics, air and water purification, food science and energy production.Polymer FilmsPolymersPolymers are large molecules made up of many repeat units. Natural polymers such as DNA and proteins are essential to life, whereas synthetic polymers such as polystyrene and polyethylene are used widely due to their functionality. Typical techniques for analysis include GPC, SEC, DSC, FT-IR and NMR.NanomaterialsNanomaterials such as carbon nanotubes, fullerenes and nanoparticles are a group of materials that measure between 1-1000nm for a single unit. Analysis techniques include AFM, electron microscopy and super resolution microscopy.
