内 容 介 绍：Secondary nanostructures inscribed onto hierarchical fibers provide additional dimensionality for tuning the surface and physicochemical properties of the materials. In general, nanoporous and nanowrinkled electrospun fibers are produced by tuning parameters such as solvent, humidity, composition, etc., without post-electrospinning treatment, while post-electrospinning treatment is required to introduce nanorods and “nanokebabs” onto a smooth fiber surface.  In contrast, by employing new design concepts, we are able to fabricate various nano/microstructured electrospun fibers with structural hierarchy and compositional complexity.  This presentation will focus on the new design concepts of hierarchically structured electrospun fibers by engineering the amorphous phase of semicrystalline polymer-based fibers through solvent vapor annealing and targeted enzymatic degradation
