چکیده

در دو دهه اخیر، مطالعات گسترده‌ای در باره تهیه نانوکامپوزیت‌های پلیمری دارای نانولوله‌های کربنی (CNTs) انجام گرفته است. نتایج به‌دست آمده حاکی از آن است که افزودن مقدار کمی CNTs، موجب افزایش رسانندگی، پایداری گرمایی، بازدارندگی شعله، مدول یانگ، مقاومت به ضربه و اتلاف صوت نانوکامپوزیت‌های پلیمری می‌شود. از چالش‌های مهم در تهیه این نانوکامپوزیت‌ها، چگونگی پراکندگی CNTs و بهبود آن در زمینه پلیمری است. از این رو، روش‌های متفاوتی با کارایی‌‌های مختلف برای دست‌یابی به پراکنش مناسب این نانوذرات در این دسته از مواد ارائه شده است. کارایی نانوکامپوزیت‌های برپایه پلی(‌آکریلونیتریل-بوتادی‌ان-استیرن) (ABS) و CNTs، سبب استفاده از آن‌ها در صنایع مختلف مانند ساخت وسایل الکترونیکی شده است. همچنین در سال‌های اخیر، این مواد نقش مهمی در فرایندهای شکل‌دهی راهبردی مانند ساخت برهم‌افزا ایفا می‌کنند که اهمیت آن‌ها را دوچندان ساخته است. در این مقاله سعی شده است تا اطلاعات به‌نسبت جامعی درباره روش‌های مختلف پراکنش این نانوذرات در زمینه ABS و مطالعه شکل‌شناسی و خواص گرمایی، مکانیکی و الکتریکی نانوکامپوزیت‌های ABS/CNTs ارائه و مقالات و نوشته‌های چاپ شده اخیر مرور شوند.

چکیده [English]

Rapid development in producing carbon nanotubes (CNTs) thermoplastics nanocomposites have been observed in the past two decades. This is because the addition of a small amount of CNTs could increase the thermal stability, flame retardency, conductivity, Young's modulus, impact resistance and sound-proofing of the polymer-based nanocomposites. One of the challenging issues for obtaining the full performance of the nanocomposites is the dispersion of CNTs in a polymeric matrix. There are several methods to achieve a good dispersion of the nanofiller throughout the polymer matrices. It should be noted that the type of method used could play an important role in dispersion of CNTs. Poly(acrylonitrile-butadiene-styrene) (ABS)/CNTs nanocomposites are used in various industries, for instance in manufacturing of the electronic devices. In recent years, there has been an increasing interest in additive manufacturing technologies in which fused deposition modeling (FDM) has the fastest growth rate by using thermoplastics such as ABS as one of the most applicable materials for this processing method. In this paper, our aim is to present some information on ABS/CNTs nanocomposites prepared using different methods and with studies on their morphologies as well as thermal, mechanical and electrical properties by reviewing the recently related published literature.
