Abstract
Plant tendril inspired helical structures hold significant promise in various applications. In this study, we advance the understanding of factors influencing the morphology of helical fibers fabricated during co-electrospinning, which is grounded in the mechanism of inducing strain mismatch within the polymer components. Our investigation encompasses a comprehensive analysis of the intrinsic curvature through an updated bilayer strip physical model. Potential factors affecting the resulting curvature of the electrospun helical fibers, including flexibility difference and charge difference within the component pair as well as the evaporation behavior of the chosen solvents for polymers, are explored through numerical simulations and experimental validation.
