چکیده

در این پژوهش نانولوله­ های کربنی آراییده شده با نانوذره­ های آهن اکسید به روش هم رسوبی هم ­زمان و با نسبت ­های نمک اولیه 2 به 1 و 4 به 1  سنتز شد. به منظور بررسی ویژگی­ های ساختاری، سطحی و مغناطیسی با استفاده از آنالیزهای میکروسکوپ الکترونی عبوری، پسماند مغناطیسی، تبدیل فوریه فروسرخ، رامان، پراش پرتو x، جذب ـ واجذب نیتروژن و محاسبه مقدارهای نقطه بار صفر مورد مطالعه قرار گرفت. نتیجه­ های به دست آمده از تحلیل ساختاری دلالت بر تشکیل نانوذره های آهن اکسید با اندازه­های nm 2/12 و nm 5/13 به ترتیب برای نسبت­ های 2 به 1 و 4 به 1 بر روی نانولوله­ های کربنی دارد. همچنین، برای همین نسبت ها رفتار ابرپارامغناطیسی با مغناطش اشباعی به ترتیب برابر با emu/g  84/11 و emu/g 9/27 دیده شده است. نتیجه­ ها نشان داد با انتخاب روش درست و بهینه سازی پارامترهای تأثیرگذار در روش سنتز نانولوله­ های کربنی مغناطیسی می­توان به طور مستقیم ویژگی­ های سطحی آن ­ها را تغییر داده و در نتیجه نانوساختاری با ویژگی­ های سطحی مشخص در گستره وسیعی از شرایط آزمایشگاهی به ­دست آورد.
