　　Trace water in organic substances often has a disadvantage over their application in industry.Distillation[1-2], pervaporation membrane[3] and absorption[4] have been always employed for trace-water dehydration.However, technology of specialty distillation is needed for the system possesses azeotropic point[5];whereas preparing the membrane with excellent performance to improve the pervasion flux and selectivity is required for pervaporation membrane technology[6].
