Abstract: Described herein are conductive fluorinated elastomeric materials and methods of making and using the same. The conductive fluorinated elastomeric materials include a fluorinated polymeric matrix and one or more high aspect-ratio fillers, wherein a surface resistance of the elastomeric material is 15 ohm/square or less and/or a bulk conductivity of the elastomeric material is 0.7 Ohm-cm or less. Also described herein are liquid fluorinated elastomeric compositions, including a fluorinated polymer, one or more high aspect-ratio fillers, and a solvent. Further described herein are molded products including the conductive fluorinated elastomeric materials as described herein and wearable devices including the molded products.
