چکیده
توزیع یکنواخت نانوذرات رس در ماتریس اپوکسی، به‌ویژه بااستفاده‌از اصلاح‌کننده‌های شیمیایی، می‌تواند به بهبود خواص نانوکامپوزیت‌ها کمک‌کند. تحقیقات نشان‌می‌دهد که اصلاح نانورس تأثیر مثبتی بر خواص مکانیکی رزین‌های اپوکسی دارد. نانوکامپوزیت‌های اپوکسی که حاوی نانورس اصلاح‌شده با گروه‌های مختلف است، به‌طور قابل توجهی استحکام کششی و مدول یانگ را افزایش‌می‌دهد. این بهبود به‌دلیل پراکنش مناسب نانوذرات و تعامل بهینۀ بین رزین و نانورس است. هم‌چنین، این مطالعه به بررسی پایداری گرمایی و تخریب گرمایی نانوکامپوزیت‌های اپوکسی می‌پردازد و نشان‌می‌دهد که افزودن نانورس به ترکیبات اپوکسی می‌تواند خواص گرمایی و مکانیکی این مواد را به‌طور قابل توجهی بهبودبخشد. به‌طور کلی، این پژوهش چنین نتیجه‌‌می‌گیرد که نانوکامپوزیت‌های اپوکسی بااستفاده‌از نانورس و نانوذرات رس اصلاح‌شده، به‌طور چشم‌گیری از نظر پایداری حرارتی و خواص مکانیکی بهبودمی‌یابد و می‌تواند در کاربردهای صنعتی به‌عنوان موادی با عملکرد بالا و مقاوم دربرابر حرارت و تخریب گرمایی به‌کاررود. این تحقیق، هم‌چنین به بررسی اثر نانورس‌های اصلاح‌شده بر ریخت‌شناسی، خواص مکانیکی، پایداری گرمایی و پیشرفت‌های اخیر درزمینۀ رزین اپوکسی و نانوکامپوزیت‌های هیبرید می‌پردازد.

چکیده English

Studies indicate that the uniform distribution of clay nanoparticles within an epoxy matrix, particularly in the presence of chemical modifiers, significantly enhances the properties of nanocomposites. Research findings demonstrate that the modification of clay nanoparticles positively impacts the mechanical properties of epoxy resins. Epoxy nanocomposites containing modified clay nanoparticles with various functional groups exhibit notable increases in tensile strength and Young's modulus. These improvements are attributed to the proper dispersion of nanoparticles and optimal interactions between the resin and clay. This study also investigates the thermal stability and thermal degradation of epoxy nanocomposites, revealing that the incorporation of clay nanoparticles into epoxy formulations can substantially enhance their thermal and mechanical properties. Overall, the research concludes that epoxy nanocomposites utilizing both clay nanoparticles and modified clay significantly improve thermal stability and mechanical characteristics, making them suitable for high-performance industrial applications that require heat and thermal degradation resistance. Additionally, this study explores the effects of modified clay nanoparticles on morphology, mechanical properties, thermal stability, and recent advancements in epoxy resin and hybrid epoxy nanocomposites.
