Paper Title:
Hydrophobic Modification of PVDF
  Abstract

For preparation of an architecture membrane with hydrophobic properties, a method combining supercritical carbon dioxide (scCO2 ) and low temperature plasma treatment was used. The effects of treating time, pressure and temperature in scCO2 fluid on surface hydrophobic property were studied. The results showed that the contact angle of the membrane that was firstly modified by low temperature plasma and then treated in scCO2 fluid was up to 141°from 80°. In addition, the optimal hydrophobic modification conditions in scCO2 were 100°C、25MPa and 6h, and the hydrophobic property of the membrane that treated by plasma improved, the most suitable time was 300s.
