چکیده | ||
نانوکامپوزیتهای بر پایهی پلیاستایرن با استفاده توام از نانوتیتانیوم دیاکسید و نانونقره (نسبت 7 به 3) به وسیلهی فرآیند اختلاط با ذوب در دمای °C190 و در دو سطح %5/0 و %1 تولید شدند. با استفاده ازمیکروسکوپ الکترونی روبشی(SEM) متصل شده با طیفنگاری پاشندگی انرژی اشعهی x (EDS)، حضور و مقادیر نانوذرات تیتانیوم و نقره تایید شد. تصاویر حاصل ازSEM نشان داد که نانوذرات به صورت مجزا و تجمع یافته وجود دارند و به تبع آن، EDS هم نشان داد که تنها سه عنصر کربن، تیتانیوم و نقره در ساختار نانوکامپوزیت وجود دارد، همچنین، نسبت نانوتیتانیوم به نانونقره حدود 10 برابر بود. نتایج حاصل از آزمون کشش نشان داد که افزودن نانوذرات منجر به کاهش جزئی مدول یانگ و تنش در نقطهی شکست نانوکامپوزیتها در مقایسه با پلیاستایرن خالص شد و از نقطه نظر کرنش در نقطهی شکست تفاوت معنیداری بین نانوکامپوزیتها و پلیاستایرن خالص مشاهده نشد (05/0˃P). تاثیر نانوذرات بر ویژگیهای حرارتی شبکهی پلیمری با استفاده از کالریمتری روبشی افتراقی و وزنسنجی حرارتی ارزیابی شد. ویژگیهای حرارتی نانوکامپوزیتها از نقطه نظر دمای انتقال شیشهای و پایداری حرارتی در مقایسه با پلیاستایرن خالص بهبود جزئی نشان داد. | ||
