✦ Synopsis

PVDF powder (0.5 g) was dispersed in N,N-dimethyl-formamide (DMF, 10 ml) at 60 8C, after stirring for 1 h and standing for 0.5 h, this solution was coated on glass substrate. The PVDF membrane was obtained after drying at 120 8C for 0.5 h.

PVDF membranes were bombarded with high-energy oxygen ion emitted by the microwave plasma in order to produce active groups [24] on PVDF membrane. In this process, plasma power in the range of 100-200 W and the plasma etching time were varied. The evacuation during the process was 12.0 Pa.
