Abstract

يتعلق الاختراع الحالي بأغشية ثنائي فلوريد متعدد الفينيل polyvinyli difluoride (PVDF) محضرة من محلول صب بما في ذلك كابا- كاراجينان kappa-carrageenan (kCg) لبوليمر حيوي كمادة إضافة تُظهر خصائص وبنية محسنة. تكون للبنية غير المتماثلة الناتجة طبقة رقيقة على السطح العلوي، طبقة فرعية مسامية ذات حجم منخفض من مساحة الفراغ الكلي ومسامية متزايدة، وطبقة إسفنجية أسفل الطبقة الفرعية. هذا يؤدي إلى طبيعة محبة للماء متزايدة، ويوفر تندية محسنة، مسامية غشاء، ونفاذية للماء- تجعل جميع هذه الخصائص المهمة الغشاء مناسبا لمجموعة واسعة من الاستخدامات. شكل 1 (أ)
