Summary: Green electrospinning is a new technology that uses a template polymer to spin a polymer from an aqueous dispersion, providing an environmentally friendly and safe method for spinning hydrophobic polymers. The study found that factors such as template polymer molar mass, total solids content, and particle/template ratio influence fiber morphology, while surfactant used, surface functionality of polymer particles, and particle size distribution also play a role. Additionally, viscosity of the initial blend, particle packing, and surface chemistry of polymer particles are important for obtaining high-quality nanofibers.
