| Abstract Scope |
Mechanical properties are critical in electrospun membranes fabricated with functional nanofibers for applications requiring durability under stress. This study investigates how varying thermal annealing conditions affect membrane performance. Tensile testing revealed that increasing annealing temperatures enhanced Young’s modulus and yield stress, shifting failure modes from ductile to brittle. Strain-at-break decreased with heat, indicating membrane stiffening. Load-unload strain cycle tests showed structural stabilization after initial deformation, suggesting improved elastomeric recovery. Anisotropic patterns and junction behavior further highlighted the structural role of fiber interactions. Bending tests demonstrated reduced flexibility with higher annealing, confirming increased rigidity. Finally, annealing enabled the creation of freestanding 3D spherical membranes—offering new directions for advanced membrane applications. Overall, this study underscores thermal annealing as a powerful tool for tuning mechanical properties and enabling versatile designs in tissue engineering, filtration, and other high-performance fields. |
