(a) Wet spinning process in which four hybrid microfibers are spun at once. (b) Optical image of fibers from the 1 ml of spinning solution wrapped around a 15 cm diameter steel stick. (c) Scanning electron microscopy (SEM) image of two hybrid microfibers twisted together. (d) Polarized optical microscopy (POM) image of a hybrid microfiber after extrusion from a syringe. (e) POM image of a hybrid microfiber that has been dried in air for 10 s. (f) POM image of a hybrid microfiber under tension after drying completely in air.
