2. Background and Purpose of Research

3. Hypothesis
The project’s combinations of parameters can create PVA, PCL and PVDF fibres of ultrafine nanometer diameters and diameters larger than 100 micrometers.

4. Electrospinning of PVA, PCL and PVDF

5. Results Effect of voltage applied on diameter

6. Results Effect of solution concentration on morphology
Fig.11. SEM image for PVDF 12% 10kV
Fig.10. SEM image for PVA 15% 15kV

7. Results Effect of standoff distance on thick fibres

8. Applications & Recommendations for Future work
Potential difference, concentration and standoff distance were varied to determine their effects on PVDF, PCL and PVA => many applications.
Wider ranges of parameters can also be studied to fully validate the results.
