چکیده

در این پژوهش ویژگی‌ها و رفتار سینتیکی پخت نانوکامپوزیت اپوکسی اکریلات/گرافن اکسید و نیز احیای صفحات اکسید گرافن حین پخت سامانه با پرتو فرابنفش در حضور یک آغازگر نوع دوم بررسی شده است. آزمون­های میکروسکوپ نوری و میکروسکوپ الکترونی عبوری (TEM) نشان داد صفحات اکسید گرافن از پراکندگی خوبی در سامانه تابش­پز برخوردارند. نتایج رئومتری نشان داد نانو کامپوزیت رفتار رقیق­شونده برشی (Shear Thinning) از خود نشان داده و ویسکوزیته سامانه در نرخ­های برشی بالا کمتر از گرانروی رزین تابش­پز است. بررسی سینتیک پخت سامانه تابش­پز با استفاده از آزمون طیف‌سنجی زیر قرمز هم­زمان (RT-FTIR)، نشان داد حضور اکسید گرافن موجب کاهش میزان پخت نمونه­ها شده است. با این وجود نتایج مربوط به محتوای ژل نمونه­های نانوکامپوزیتی نشان داد با افزایش شدت و زمان تابش پرتو فرابنفش شبکه پلیمری با پخت کامل ایجاد می­شود. همچنین نتایج بررسی مقاومت الکتریکی نانوکامپوزیت نشان داد احیای تابشی نانو صفحات اکسید گرافن حین تابش فرابنفش انجام شده و مقاومت الکتریکی آن در کمتر از 150 ثانیه تا 50 درصد کاهش پیدا می­کند.

چکیده [English]

This paper investigates the curing behavior of epoxy acrylate/graphene oxide UV curable nanocomposite. Also, the simultaneous reduction of GO nanoplates during UV curing of nanocomposite containing type II photoinitiator was studied. Optical and transmission electron microscopies showed good GO nanoplate dispersion in UV curable matrix. Rheological results illustrate the shear thinning behavior of UV-curable nanocomposites so that in high shear rates, the viscosity of nanocomposite is lower than that of UV-curable matrix. Real-time FTIR analysis shows that GO causes a reduction in the curing rate and final conversion of the UV-curable system. However, gel content results show that more UV intensity and curing time led to perfect UV curing of the nanocomposite. An electrical resistance study on the UV-curable nanocomposites made GO reduction during UV irradiation, evidenced by halved electrical resistance of the nanocomposite in less than 150 seconds.
