A Model for Surface Charge Density Effects with High Evaporation Rates in Electrospinning

摘要

@@A mathematical model is being developed for nanofiber processing incorporating dry spinning and electrospinning principles. The development of the model is directed at the identification of parameters which influence fiber characteristics, e.g. Solvent concentration, temperature, viscosity, and electrical field. Electrospinning is a method of spinning nanoscale fibers that uses an electric field to propel a stream of polymer solution to create the fiber. Although much research has been done on the process itself, its wide-scale adoption has been inhibited by a lack of predictive control on the fiber properties. By developing an accurate computational model, enhanced process control and the production of fibers with desired properties can be attained. A mathematical model was developed that incorporates dry spinning and electrospinning principles. Its development was directed at the prediction of parameters which influence fiber characteristics, e.g. Solvent concentration, temperature, viscosity, and electrical field.
