Electrospinning of Nanofiber for Water Purification Applications Tran Thuy Dung Hwa Chong Institution

Background and Purpose of Research

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

Electrospinning of PVA, PCL and PVDF

Results Effect of voltage applied on diameter

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

Results Effect of standoff distance on thick fibres

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.
