Abstract

A polymeric composition including a blend of poly(vinylidine fluoride) (PVDF), poly(methyl methacrylate) (PMMA), carbon nanofibers, and poly(tetrafluoroethylene) (PTFE) particles is described and claimed. The polymeric composition may be coated onto a substrate and dried to form a film adhered to the substrate. The film optionally exhibits an electrical conductivity of about 10 Siemens per meter (S/m) to about 310 S/m and an electromagnetic interference shielding of about 32 decibels. Further, a coated substrate is provided including a substrate and a film adhered to the substrate, where the film includes a polymeric composition comprising a blend of PVDF, PMMA, carbon nanofibers, and PTFE particles.
