چکیده

در این مقاله از صفحات اکسید گرافن اصلاح سطحی شده توسط بنزایمیدازول به عنوان نانوذرات تقویت کننده پوشش اپوکسی استفاده شد. در این راستا، پس از سنتز اکسید گرافن و جذب فیزیکی مولکول‌های بنزایمیدازول بر روی آن، نانوصفحات اکسید گرافن اصلاح شده توسط بنزایمیدازول به همراه نانوذرات اصلاح نشده در بستر رزین اپوکسی به طور کامل پخش شدند. خواص فیزیکی مکانیکی پوشش های حاصل توسط آزمون DMTA و کشش مورد بررسی قرار گرفت. همچنین با استفاده از میکروسکوپ الکترونی روبشی، ریخت‌شناسی سطح شکست پوشش‌ها و چگونگی پخش نانوصفحات بررسی شد. نتایج نشان داد که مولکول‌های بنزایمیدازول به صورت موفقیت‌آمیزی با ایجاد پیوندهای غیر کووالانسی، سطح اکسیدگرافن را اصلاح نموده است. همچنین با افزودن نانوذرات اصلاح شده به پوشش، استحکام کششی نهایی، مدول یانگ، کرنش تا نقطه شکست و انرژی در نقطه شکست به ترتیب 81، 15، 310 و 207 % نسبت به پوشش اپوکسی بدون نانوذرات افزایش یافت. این بهبود خواص فیزیکی-مکانیکی پوشش به دلیل پخش بهتر نانوصفحات در پوشش و اتصال قوی‌تر مابین نانوصفحات با رزین است.

چکیده [English]

In this paper, the graphene oxide nanosheets modified by benzimidazole were used as the epoxy coating reinforcing nanoparticles. In this way, after synthesizing of graphene oxide and physically adsorption of benzimidazole molecules on them, the modified graphene oxide nanosheets and the unmodified graphene oxide were dispersed in the epoxy matrix. The physical-mechanical properties of the coatings obtained were evaluated by DMTA and tensile tests. In addition, by a scanning electron microscope (SEM) the coating fractured surface morphology and the degree of nanoparticle dispersion in the coatings were studied. The results showed that the benzimidazole molecules could successfully modify the graphene oxide nanosheets surface via noncovalent bonds. Furthermore, the ultimate tensile strength, Young's modulus, strain at break, and energy at break were increased 81%, 15%, 310%, and 207%, respectively, compared to the neat epoxy coating. This improvement in physical-mechanical properties of the coating may be attributed to the better dispersion of the nanosheets in the coating as well as the stronger interactions between the nanosheets and the epoxy resin.
