Poly(vinylidene fluoride-co-hexafluoro propylene)membranes prepared via thermally induced phase separation and application in direct contact membrane distillation
文献摘要：
A non-toxic and environmentally safe diluent,acetyl tributyl citrate,was employed to prepare poly(vinylidene fluoride)-co-hexafluoropropylene membranes via thermally induced phase separation.Effects of the polymer concentration on the phase diagram,membrane morphology,hydrophobicity,pore size,porosity and mechanical properties(tensile stress and elongation at break)were investigated.The results showed that the pore size and porosity tended to decrease with increasing polymer concentration,whereas the contact angle,liquid entry pressure and mechanical properties showed the opposite trend.In direct contact membrane distillation operation with 3.5 wt-％sodium chloride solution as the feed solution,the prepared membranes performed high salt rejection(＞99.9％).Furthermore,the prepared mem-branes retained excellent performance in long-term stability tests regarding the permeate flux and salt rejection.
