Mesoporous fluoropolymer nanospheres of 200–300 nm in size were directly prepared via one‐pot plasma polymerization and deposition of solid fluoropolymer nanospheres, followed by controlled argon plasma dry etching. Films of the assembled mesoporous fluoropolymer spheres exhibited an ultra‐low dielectric constant of about 1.7. Adsorption of surface‐modified PtFe nanoparticles of about 3 nm in size onto the mesoporous structure produced mesoporous fluoropolymer spheres with ferro‐magnetic properties.
