Table 3 Morphology-based optimization of H-PCL fraction for electrospinning.
H-PCL Fraction (% w/w) | Oriented Fibers – Observation | Random Fibers – Observation |
|---|---|---|
100% | Continuous, well-aligned fibers | Dense, uniform continuous fiber network |
90% | Continuous fibers | Continuous fibers |
80% H-PCL | Continuous fibers | Continuous but mild heterogeneity in thickness |
70% H-PCL | Continuous fibers | Continuous fibers with localized thick filaments |
60% H-PCL | Continuous with minor diameter variation | Continuous fibers with occasional fused junctions |
50% H-PCL | Continuous; slightly less uniform alignment | Continuous fibers; mild structural irregularity |
40% H-PCL | No fiber formation | Intermittent fibers with bead formation |
30% H-PCL | No electrospinning (jet not initiated) | Discontinuous jets and beaded structures |
20% H-PCL | No electrospinning (jet not initiated) | Electrosprayed droplets and non-fibrous deposits |
