چکیده

نانوکامپوزیت ­های گرماسخت، به ­دلیل استحکام و خواص فیزیکی و مکانیکی ویژه در مقایسه با مواد فلزی، کاربرد بسیاری در ساخت وسایل خانگی، الکتریکی، پوشش ­ها و وسایل ورزشی و بهداشتی دارند. خواص گرمایی نانو­کامپوزیت­ های اپوکسی به چسبندگی بین نانوذرات و ماتریس بستگی دارد. همچنین، طراحی نانوکامپوزیت­ های اپوکسی با کیفیت و بازده زیاد و خواص فیزیکی و مکانیکی مناسب نیازمند فهم و دانش پدیده­ هایی است که در زمان  واکنش پخت انجام می ­شوند. واکنش رزین اپوکسی و عامل پخت و  نیز بررسی سینتیک پخت نقش مهمی در کنترل تغییر شکل ساختار و خواص فیزیکی و مکانیکی کامپوزیت ها دارد. بررسی و مطالعه پراکنش نانوذرات و انتخاب روش اختلاط مناسب، می­ تواند موجب بهبود واکنش پخت یا شبکه ­ای­ شدن نانوکامپوزیت ­های اپوکسی شود. همچنین، این کار می ­تواند از کلوخگی نانوذرات جلوگیری کند که بر واکنش­ های گرمایی اثرگذارند. نانوذرات آهن اکسید اصلاح ­شده باعث کاهش انرژی فعال­سازی واکنش می ­شود و زمان واکنش پخت را کاهش می­ دهد. زمان و دمای واکنش، دو عامل مهم  برای ارزیابی واکنش­ های شیمیایی پخت هستند. تحلیل مدل­سازی سینتیک پخت نانوکامپوزیت­ های اپوکسی، راه­ حلی برای غلبه بر مشکلات واکنش­ های گرمایی است که طی واکنش ­های پخت روی می­ دهند. در این مقاله، مدل­سازی سینتیک پخت نانوکامپوزیت­ های اپوکسی و اثر افزودن نانوذرات آهن اکسید اصلاح ­شده و نشده بر مقدار انرژی فعال­سازی، شاخص پخت، خواص رئولوژیکی، مکانیکی و گرمایی معرفی می­ شوند.

چکیده [English]

Thermoset nanocomposites, due to their strength and special physical and mechanical properties compared to metal materials, are widely used in the manufacture of household appliances, electrical appliances, coatings and sports equipment, and sanitary wares. The thermal properties of epoxy nanocomposites depend on the adhesion between the nanoparticles and matrix. Also, designing high quality and efficient epoxy nanocomposites with suitable physical and mechanical properties requires understanding the phenomena that occur during the curing reaction. The reaction of epoxy resin and curing agent as well as the study of curing kinetics play an important role in controlling the deformation of the structure and physical and mechanical properties of the composites. Investigating the dispersion of nanoparticles and selecting the appropriate mixing method can improve the curing reaction or crosslinking of epoxy nanocomposites. It can also prevent the agglomeration of nanoparticles, that affect thermal reactions. Modified iron oxide nanoparticles reduce the reaction activation energy and the curing time. Reaction time and temperature are two important factors for evaluating chemical curing reactions. Modeling analysis of curing kinetics of epoxy nanocomposites is a solution to overcome the problems of thermal reactions that occur during the curing reactions. In this paper, the curing kinetics modeling of epoxy nanocomposites and the effect of adding modified and unmodified iron oxide nanoparticles on the amount of activation energy, curing index, and rheological, mechanical and thermal properties are introduced.
