چکیده
Three different methods, Hummers method, modified Hummers method and improved Hummers method were used for the preparation of graphene oxide (GO). Among these methods, improved Hummers method gave the best oxygen-containing functional groups and the distance between the sheets was more than graphene oxide prepared by two other methods. Poly (ethylene terephthalate) was functionalize by chemical agents and graphene oxide was spin coated on the substrate, due the chemical interaction between carboxylic acid, hydroxyl and epoxy groups, with hydroxyl groups on PET, the stability after bending was improved and reduction by hydrazine vapor was used to reduce GO. FTIR, XRD, contact angle, Raman and SEM were used for characterizationکلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
