In 1902, Morton and Cooley discovered the electrospinning process, the way it is known now and filed US patents. Formhals then investigated the problem for about a decade and obtained nine US patents on different aspects of electrospinning. These patents identified a number of key issues and their potential solutions to optimize their goal of manufacturing “fine fibers”. Unfortunately, due to technology limitations, they did not realize the making of nanofibers nor their significant application potentials.
In 1995, Doshi and Reneker re-introduced the electrospinning process, by then scanning electron microscope (SEM) was commonly available and they rightly place the significance of nanofibers in perspective. They clearly identified a myriad of applications for the electrospun nanofibers in as diverse fields as structures, textile, membrane, and biomedical engineering. When Doshi and Reneker re-introduced the century old process “electrical spinning”, they also coined the more convenient term “electrospinning”.
