28. A method of manufacturing a long-range ordered fiber comprising the steps of:
-
a. Formation of an initial fiber by electrospinning a first solution phase or a first melt phase, wherein said first solution phase or said first melt phase comprises a block copolymer or a copolymer/homopolymer blend and wherein said copolymer comprises polymers of chemically dissimilar monomers; and b. Annealing said initial fiber to form a fiber comprising long range order selected from the list comprising concentric lamellae, cylinders, aligned spheres and stacked disks. - View Dependent Claims (33, 34, 36, 37, 40, 41, 47, 49, 52, 57, 68, 70, 71, 72)
