Hypothesis
The incorporation of cellulose nanocrystals and cellulose nanofibres will enhance the mechanical properties and water filtration performance of polysulfone/polyvinylpyrrolidone-based membranes.
Conclusion
The study found that membranes reinforced with cellulose nanocrystals and cellulose nanofibres exhibited improved mechanical properties and higher water flux, with the PSf/PVP/CNC-0.5 membrane showing the best performance.
Supporting Evidence
- PSf/PVP/CNC-0.5 had the highest distilled water flux of 475.5 L/m2.h.
- PSf/PVP/CNF-1 exhibited the stiffest behavior with an elasticity modulus of 70.63 MPa.
- PSf/PVP/CNC-1 had the best organic matter removal efficiency.
Takeaway
This study shows that adding tiny bits of plant material to water filters can make them work better and last longer.
Methodology
The membranes were produced using the phase inversion method and characterized for morphology, mechanical properties, and filtration performance.
Limitations
The study did not explore long-term performance or the effects of varying environmental conditions on membrane efficiency.
