Fabricating multi-material nanofabrics using rotary jet spinning

Multi-material nanofiber composites have recently attracted attention, as they introduce new opportunities for regulating mechanical, electrical, and biological properties. Here we present a novel manufacturing method for multimaterial composite nanofabrics. Using infrared spectroscopy and tensile testing, we compare the mechanical and structural properties of multi-material fabrics and single fiber blends. We find that multi-material nylon/polyurethane fabrics are tougher than their pure components, and that mechanical properties of composite nanofabrics can be tuned by varying the polymer ratio and composition. The capability of this system to fabricate nanotextiles using orthogonal solvents is also demonstrated.
