Abstract:

In a typical coaxial electrospinning process, we fabricated TiO2 micro/nanofibers with distinct hierarchical structure by controlling the flow rate and the concentration of the inner fluid. There are “microporous”, “vesicle” , “articuliform” and “tube” structure four kinds of typical morphology in the cores of the composite nanofibers. It is a quite simple and powerful method for fabricating hollow fibers with controllable structures, which will have wonderful applications in novel bioinspired materials.
