Nanofiber Alignment on a Flexible Substrate: Hierarchical Order from Macro to Nano

A simplified approach to constructing a composite material comprised of aligned electrospun nanofibers onto a flexible substrate consisting of a microfilament yarn is presented. The metal-coated knit patterns of the microfilament yarn play the role of the parallel electrode, required for the alignment of electrospun nanofibers. Hybrid materials with knitted textile as a support material and aligned high-surface-area nanofibers could represent ideal materials for use in the filtration, optical, and biomedical industries.
