Abstract

A method of electrospinning fibers is disclosed. The fibers have an inner core surrounded by a porous outer shell. The method comprises co-electrospinning first and second liquids as core and shell respectively, the second liquid surrounding the first liquid in a jet issuing from a Taylor cone, wherein the first and second liquids are miscible or semi-miscible with each other, such that pore generation is driven in the shell of the fiber. The liquids may be solutions or melts. The electrical conductivity, viscosity, miscibility and other parameters of the liquids determine the structure of the produced fibers. As well as producing fibers having a porous shell there are described methods of co-electrospraying porous beads as well as core-shell vesicles having a porous shell. The methods may be used to produce hydrogen storage fibers, vesicles and beads. The methods may also be used for producing controlled drug-delivery fibers, vesicles and beads.
