摘要： A method comprises introducing a fluid composition into one or more electrically insulating emitters, and applying voltage to the fluid to cause ejection of the solvent from the fluid after it exits the emitter. The fluid composition comprises first material having a dielectric constant greater than ˜25 and polymer mixed into liquid solvent having a dielectric constant less than ˜15, or polymer mixed into solvent having a dielectric constant greater than ˜8. Voltage can be applied to the fluid composition via a conductive electrode immersed in the fluid, or positioned outside and adjacent to the emitters. Conductivity of the fluid composition can be less than ˜100 μS/cm. A composition of matter comprises nanofibers formed by the method.

摘要： A first method comprises: dissolving a polymer in a terpene, terpenoid, or aromatic solvent to form a polymer solution; dissolving a salt in a polar organic solvent to form a salt solution; and mixing the salt solution and the polymer solution to form a mixture. The salt and the polar organic solvent do not cause substantial precipitation of the polymer upon mixing with the polymer solution. A resulting terpene, terpenoid, or aromatic solvent phase of the mixture is suitable for forming fibers by electric-field-driven spinning from one or more spinning tips onto a target substrate. A composition comprises the terpene, terpenoid, or aromatic solvent phase of the mixture resulting from the method. A second method comprises forming fibers by electric-field-driven spinning of the first composition from one or more spinning tips onto a target substrate. A second composition comprises the fibers formed by the second method.
