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.

Abstract: Embodiments of the present disclosure relate to a photomask. The photomask may include: a substrate; and one or more pixel units formed over the substrate. Each pixel unit may include: at least one polymer crystal element configured to interact with extreme ultraviolet (EUV) light based on an orientation of the polymer crystal element; and a plurality of electrodes configured to control the orientation of the polymer crystal element by applying voltage across the polymer crystal element. Each pixel unit is controlled by the respective plurality of electrodes independently, and the one or more pixel units generate a pattern for lithography upon exposure to the EUV light.
