A method comprises: dissolving an aromatic side chain polymer in a terpene, terpenoid, or aromatic solvent; dissolving an inorganic salt in a polar organic solvent; mixing the salt solution and the polymer solution; and using a predominantly terpene, terpenoid, or aromatic solvent phase of the mixture as electrospinning fluid. The fluid is electrospun from spinning tip(s) onto a target substrate. The inorganic salt and the polar organic solvent are chosen so as not to cause substantial precipitation of the polymer upon mixing with the polymer solution. The terpene, terpenoid, or aromatic solvent can comprises D-limonene, the aromatic side chain polymer can comprise polystyrene, the polar organic solvent can comprise dimethyl formamide, and the inorganic salt can comprise LiCl, AgNO3, CuCl2, or FeCl3. The method can further comprise electrospinning the fluid with the fluid and spinning tips electrically isolated from a voltage source that drives the electrospinning. |
