چکیده

در این پژوهش از روش انفجار الکتریکی سیم برای تولید نانوکامپوزیت آلومینیوم-CNT در محیط استون استفاده شد. به‌منظور سنتز نانوکامپوزیت آلومینیوم-CNT، ابتدا نانولوله­های کربنی توسط دستگاه فراآوا در استون پخش شدند. سپس سیم آلومینیومی در این محیط منفجر شد. نمونه­های سنتز شده به‌منظورمشخصه­یابی تحت آزمون­های طیف سنجی FTIR وTEM قرار گرفتند. نتایج نشان داد که نانوذرات سنتز شده کروی شکل و دارای میانگین اندازه ذرات 4 نانومتر هستند. هم‌چنین نانوذرات تولید شده در استون پایدار ماندند. نتایج نشان داد که برهم‌کنش خوبی بین نانوذرات آلومینیوم و نانولوله­های کربنی در محیط استون وجود دارد. در نهایت می­توان نتیجه گرفت که استون، محیطی مناسب برای سنتز نانوکامپوزیت آلومینیوم-CNT است چون در این محیط کامپوزیتی یکپارچه با توزیع مناسب نانوذرات به‌دست می­آید.

چکیده [English]

In this study, electrical wire explosion has been used to produce aluminum carbon nanotube (Al-CNT) nanocomposite particles in acetone medium. In order to synthesize Al-CNT nanocomposites, initially, CNTs were ultrasonically dispersed. Then, aluminum wire was exploded in this medium. Synthesized samples were characterized by Fourier Transform Infrared (FTIR) spectroscopy and Transmission Electron Microscopy (TEM) methods. The results exhibited formation of spherical nanoparticles in the medium. The average diameter of nanoparticles was 4 nm. Moreover, attained nanoparticles remained stable in acetone. Results revealed a good interaction between aluminum nanoparticles and CNTs in this medium. It is concluded that acetone is a suitable medium for synthesizing Al-CNT nanocomposite as appropriate dispersion of Al-CNT nanoparticles can be achieved in this medium.
