The syntheses of inorganic metal and polyolefinic nanoparticles by means of fluorous polymers are presented. The production of silver and copper particles is utilized by laser ablation in an organic solvent and in situ functionalized with a statistical amphiphilic terpolymer bearing fluorinated side chains. The surface modified particles are then homogenously incorporated into poly(pentafluorostyrene) to simulate a PTFE matrix, often used for implants. The antibacterial properties of the silver particles are studied with E.coli bacteria. For the synthesis of high molecular weight polyolefine nanoparticles, nonaqueous Oil-in-Oil emulsions based on a perfluorinated solvent and a non-coordinating hydrocarbon were utilized for the polymerization of gaseous ethylene and propylene. In order to prevent phase separation of the immiscible solvents, an appropriate blockcopolymer was designed consisting of a lipophilic and a strongly fluorophilic segment. In contrast to most waterborne heterophase techniques, the presented system can be employed for water sensitive monomers and catalysts.
