AI Article Synopsis
- Nanofiber membranes were created from expanded polystyrene (EPS) waste mixed with poly(vinylpyrrolidone) (PVP) for water filtration through electrospinning.
- The membranes showed a smooth texture and consistent size, with physical properties varying based on the concentration of the EPS/PVP solution, affecting viscosity and surface tension.
- These membranes demonstrated a high rejection rate of 99.99%, providing an eco-friendly solution to reduce EPS waste while offering an effective alternative for water filtration.
Article Abstract
Nanofiber membranes were successfully synthesized from expanded polystyrene (EPS) waste with the addition of poly(vinylpyrrolidone) (PVP) for water microfiltration using the electrospinning method. The EPS-based nanofiber membranes exhibited a smooth morphology and were uniform in size. The concentration of the EPS/PVP solution changed some of the physical parameters of the nanofiber membrane, such as viscosity, conductivity, and surface tension. Greater viscosity and surface tension increase the nanofiber membrane diameter, whereas the addition of PVP results in hydrophilicity. Additionally, increasing the pressure increased the flux value of each variation of the nanofiber membranes. Furthermore, the rejection value was 99.99% for all variations. Finally, the use of EPS waste for nanofiber membranes is also beneficial for decreasing the amount of EPS waste in the environment and is an alternative to the current membranes available in the market for water filtration applications.
