Flower‐shaped carbon fibers are created from novel processes using polyethylene‐based precursors by A. K. Naskar and co‐workers. Such patterned, continuous carbon fibers have tunable cross‐sections, from hollow circular to gear‐shaped, and tailored properties arising from the highly versatile fabrication methods described on page 2386 . The fibers exhibit ordered graphitic structures near the surface and porous disordered carbon near the core. These porous fibers have 3–30‐fold higher BET surface areas relative to solid fibers of similar construction, rendering them amenable to myriad applications.
