Summary

Sulfonated poly(ether ether ketone) nanofibers were prepared using electrospinning. These novel nanofibers form membranes with tunable pore distribution and permeability, suitable for advanced filtration applications.

Area of Science:

  • Polymer science and materials engineering
  • Nanotechnology and advanced materials

Background:

  • Modern fiber technology and novel polymers enable new material products.
  • Electrospinning is a key technique for producing polymer nanofibers for membranes.
  • Membrane performance depends critically on surface properties, pore distribution, and morphology.

Purpose of the Study:

  • To prepare and characterize sulfonated poly(ether ether ketone) nanofibers and membranes.
  • To evaluate the potential of these nanofibrous membranes for filtration applications.

Main Methods:

  • Electrospinning was employed to fabricate sulfonated poly(ether ether ketone) nanofibers.
  • Scanning electron microscopy (SEM) was used for surface and cross-sectional morphology analysis.
  • Pore size distribution and pure water permeability were measured to characterize the membrane.
