Abstract

Polyether sulfone (PES)/polyethylene oxide-polypropylene oxide-polyethylene oxide triblock copolymer (P123

PEO20PPO70PEO20

Ma 5800) nanofibrous membrane was prepared via electrospinning. The influence of P123 content on viscosity and surface tension of spinning solution was investigated as well as the effect on structures and properties of the formed nanofibrous membranes. The results showed that the viscosity and surface tension of spinning solution increased from 300 to 1000 mPa·s and 36.5 to 37.8 mN·m-1 with increasing P123 content from 3% to 9%

respectively. The diameter of the obtained PES/P123 nanofibers was about 360 nm. The formed PES/P123 nanofibrous membranes had a uniform distribution

smooth surface and good mechanical and swelling properties. They also had large specific surface area (>39 m2·g-1) and porosity

and could be used as catalyst support.
