In this study, the chemical structure at the interfaces of nanocomposite thin films, consisting of MgF 2 nanoparticles and a plasma polymer fluorocarbon (PPFC) matrix, was analyzed to elucidate the relationship between fluorine dispersion and surface properties. Using self‐made MgF 2 –carbon nanotube–polytetrafluoroethylene ternary composite sputtering targets, MgF 2 nanoparticles were successfully embedded in the PPFC matrix through sputtering. The spectrometric analysis showed that the fluorine atoms transfer at the nanoparticle interface created a carbon‐rich region in the PPFC polymer matrix, resulting in higher thin film hardness. The optimized MgF 2 nanoparticle/PPFC matrix thin film showed that surface hardness reached 4.32 GPa, and it also exhibited high optical transparency and water repellency. MgF 2 –PPFC nanocomposite thin film could be applicable to protective optical coatings for display and automotive windows.
