We show that poly(ethylene oxide) (PEO) solutions formulated using solvent mixtures of acetonitrile (AcN) and water can be centrifugally spun into fibers. find spinnability fiber morphology depend on choice if polymer concentration, solution shear rheology, the number entanglements, extensional relaxation time, parameters for centrifugal spinning are nearly matched. obtain an intrinsic map vola...
