摘要：
Fibers that are formed from a thermoplastic composition that contains a polymer and high surface area nanostructures are provided. The fibers have a voided structure and low density while maintaining good strength characteristics. To achieve such a structure, a blowing agent in the thermoplastic composition is activated during extrusion to form bubbles in the fibers. The high surface area nanostructures in the formed fibers can be formed of or carry the blowing agent and can enhance the strength of the fibers and compensate for the non-load bearing voids of the fibers.
