Abstract

يتعلق الاختراع الحالي بغشاء تناضحي osmotic membrane يشتمل على طبقة فعالة active layer وطبقة دعم مُركبة composite support layer. تسمح الطبقة الفعالة بشكل انتقائي بمرور جزيئات الماء ولكنها تمنع وترفض مرور بعض الأيونات المُذابة dissolved ions الأخرى. تتضمن طبقة الدعم المُركبة جانب والذي يكون ملتصق بالطبقة الفعالة ويشتمل على طبقة فرعية من ألياف متناهية الصغر electrospun-fiber sub-layer وطبقة فرعية لعكس الطور phase-inversion sub-layer. شكل5
