In 60 s, the inert surface of polystyrene material is converted into a functional platform onto which organic molecules and metal particles can be anchored. A polystyrene (PS) matrix is blended with a small amount of a diblock copolymer additive engineered to both segregate at the material surface and be able to involve chemical reaction. Indeed, poly(pentafluorostyrene) (PSF) contains surface active fluorine atoms and the nucleophuge para-fluorine atom that allows nucleophilic substitution with thiols. Films of blend of PS matrix and PS-b-PSF additive are submitted to a microwave annealing to accelerate the spontaneous surface segregation of fluorine low surface energy atoms. XPS was performed to find that the optimal annealing conditions was a treatment at 30 W during 60 s. With this procedure, a blend of 5 w% in additive can lead to a surface composed of 13 at% of fluorine atoms corresponding to 55 w% of diblock. The pentafluorostyrene units decorating the surface were used as anchors to immobilize gold nanoparticles via the para-fluoro-thiol click reaction. %G English %2 https://univ-pau.hal.science/hal-02911028/document %2 https://univ-pau.hal.science/hal-02911028/file/paper%203.pdf %L hal-02911028 %U https://univ-pau.hal.science/hal-02911028 %~ CNRS %~ UNIV-PAU %~ IPREM %~ INC-CNRS %~ IPREM-PCM %~ TEST-HALCNRS %~ UPPA-OA %~ TEST2-HALCNRS
