Figure 3: Cartoon illustration of a cotton candy machine comprised of a large cylindrical drum (called the COLLECTOR), at the center of which is a heated container (which we call EMITTER) in which we typically pour moist sugar (3 parts of sugar with 1 part of water + food coloring if you wish). The container spins at seveal 1000 RPM and as the viscous caramelized sugar fluid oozes out of the holes in the EMITTER, and the centrifugal force splashes the caramelized sugar fluid droplets, and in the process, extending them into thin crystalline nanofibers. Applying a low electric field (12-24 V) between the emitter and collector, and replacing sugar with molten polymer, provides a high throughput electrospinning system one can construct at one's home with simple parts.
