Extraction of a Component from Bicomponent Nanofibers

The detailed topology of the porous fiber, consisting of interconnected volumes and channels produced by leaching or annealing away of one component, depends on the phase morphology of that component. 

Under appropriate eiectrospinning conditions nanofibers of a single polymer, with their surface patterned into closely spaced regular or irregular pores, are obtained. Coupled with the already small average fiber diameters, diese surface features can potentially yield remarkably high specific areas, with
