تاكلالملخص
تم استخدام عملية الطلاء الدوراني في هذه الدراسة لإنشاء مركبات نانوية لبوليمر إيثينفينيل أسيتات المشترك المقوى بجسيمات نانوية نانو تيتانيا بنسب مختلفة (50 ، 100 ، 150 جزء / مليون). باستخدام التحليل الطيفي للأشعة تحت الحمراء (FTIR) ، تم فحص أنواع مختلفة من التفاعلات بين TiO2 و EVAc. تم استخدام مسعر المسح الأحادي لدراسة درجة انصهار الأغشية الرقيقة. كما تمت دراسة مقاومة الأغشية الرقيقة المقاومة للتآكل باستخدام الطريقة الكهروكيميائية
أظهرت النتائج أن إضافة جزيئات TiO2 النانوية عزز الخصائص الحرارية للأغشية الرقيقة المركبة النانوية ، وزاد Tm من 66 درجة مئوية إلى 71 درجة مئوية ، وأظهرت نتائج تحليل FTIR أن TiO2 و EVAc النانويان يتفاعلان جسديًا. يظهر السلوك المضاد للتآكل أن تيار التآكل ينخفض من 188 مللي أمبير إلى 1 nA ويزيد مقاومة التآكل. بالإضافة إلى ذلك ، زادت فعالية التثبيط من 0.0 إلى 99٪. مع إضافة Nano TiO2 مع 150 جزء في المليون إلى الأغشية الرقيقة
