A modified electrospinning setup was developed to produce nanofiber yarns from twisted assemblies of polyacrylonitrile (PAN), polyvinylidene fluoride trifluoroethylene (PVDF‐TrFE) and polycaprolactone (PCL). Yarn twist and fiber diameter were tuned by varying the collector speed. Schauer and co‐workers find that that porosity is dependent on polymer type, rather than twist angle, and that the porosity of nanoyarns is significantly higher than nonwoven mats. All the yarns have a high strain‐to‐failure (with PVDF‐TrFe and CL yarns being higher than PAN yarns) which is important for integration into textiles to be used in applications such as wearable health monitoring systems.
