摘要：

An overview is given of a new and potentially useful expansion of the scope of electrospinning, namely, the encapsulation of aqueous domains within thin polymer fibers. It is demonstrated that EVA fibers containing aqueous reservoirs are easily electrospun and that osmotic swelling can lead to expansion and eventually the bursting of these reservoirs.
