Abstract

There is provided a hollow fiber and method of making. The hollow fiber has an inner-volume portion having a first-core portion and one or more hollow second-core portions. The first-core portion has nanostructures and one or more first polymers. The nanostructures act as an orientation template for orientation of the first polymers in a direction parallel to a longitudinal axis of the fiber. The first-core portion is in contact with and encompasses the hollow second-core portions. The hollow fiber further has an outer-volume portion having one or more second polymers. The outer-volume portion is in contact with and completely encompasses the inner-volume portion. The inner-volume portion has at least one of a tensile modulus and a strength that are higher than at least one of a tensile modulus and a strength of the outer-volume portion.
