چکیده | ||
در این مقاله، رفتار کمانشی گرافن عاملدار شده کووالانسی با نایلون 6 و 6 در محیطهای خلأ و آبی با استفاده از شبیهسازی دینامیک مولکولی مورد تحلیل و بررسی قرارگرفته است. با محاسبه نیروی کمانش بحرانی و کرنش گرافن عاملدار، اثرات درصد وزنی، الگوهای مختلف توزیع و شکلهای اتصال بر روی این مقادیر مطالعه شده است. نشان داده میشود که گرافن دارای کرنش و نیروی بحرانی بسیار کوچکی میباشد. با عاملدار کردن کووالانسی، نیروی بحرانی گرافن عاملدار شده افزایش مییابد که در حضور مولکولهای آب، چشمگیرتر است. نتایج شبیهسازی نشان میدهد که کرنش بحرانی بهاندازه نیروی بحرانی به حضور مولکولهای آب حساس نمیباشد. همچنین، با افزایش درصد وزنی گروههای عاملی، نیروی بحرانی افزایش مییابد. در مقابل، کرنش بحرانی با عاملدار کردن گرافن کاهش مییابد و کرنش بحرانی گرافن عاملدار شده با افزایش درصد وزنی کاهش مییابد. نتایج حاصل از این مطالعه میتواند بهعنوان معیاری برای نانوکامپوزیتهای مبتنی بر گرافن استفاده شود. | ||

چکیده [English] | ||
In this research, the buckling behavior of covalently functionalized graphene with nylon 6,6 in vacuum and aqueous environments is investigated employing the molecular dynamics (MD) simulations. The critical buckling force and strain of functionalized graphene are computed and the effects of weight percentage, different distribution patterns and attachment configurations on these values are investigated. Graphene is demonstrated to have very small critical strain and force. By covalent functionalization, the critical force of functionalized graphene increases which is more considerable in the presence of water molecules. Moreover, it is found out that critical strain is not as sensitive as critical force to the presence of water molecules. Also, by increasing the weight percentage of functional groups, the critical force increases. By contrast, the critical strain reduces by functionalization and the critical strain of functionalized graphene reduces as the weight percentage increases. The results of this study can be used as the benchmark for the graphene-based nanocomposites. | ||
