Abstract
Because of its large range of sizes and its customizability, porous polymer materials have gained interest in many applications including energy storage , tissue engineering, and filtration, and environmental cleanup. One vast subfield of macroporous polymer materials is electrospun fibrous materials which are porous membranes made of a network of nano- to micron-sized fibers. Although there has been reports on using polymer blends to functionalize the fiber surface in order to create highly porous activated carbon fiber, there have been very few reports of activated carbon fibers with highly ordered hierarchical structures with the same control as with comparative polymeric hierarchically ordered microstructures such as the polymer Nano Fiber Shish Kebab (NFSK) structures. For the first time reported, PVDF-PVDF NFSKs were created and the crystalline structure was characterized. These PVDF-PVDF NFSKs were also used as a precursor for carbonization and the successful maintenance of the original NFSK morphology allowed for the creation of the first reported fully carbon NFSK. With future research into precise control of PVDF-PVDF NFSK dimension and this successful procedure of creating a fully carbon highly ordered hierarchical structured NFSK via carbonization can lead to creation of activated carbon materials with highly desirable, finely tuned, meso- and macroporous microstructure for multifunctionality.
