چکیده

The present work explores a facile route to prepare a durable conductive fabric by using reduced graphene oxide and polypyrrole. Prior to coating of active materials, polyester surface experienced a modification which resulted in high uptake of materials. Then, dipcoating approach was used to deposit graphene oxide on the modified polyester. After reduction of graphene oxide, polypyrrole particles grew on the fabric surface through an in situ polymerization method. SEM, XRD,  FTIR, and TGA were employed to investigate the morphology and chemical structure of the samples. A high electrical conductivity of ۰.۹۸ S.cm-۱ was obtained which arises from establishing the numerous conduction routes in the structure. A mere decrease in conductivity after ۲۰ laundry cycles confirms the excellent washing durability of the conductive fabric. Moreover, a high specific capacitance of ۸.۳ F.g-۱ was recorded for this fabric by cyclic voltammetry in a three-electrode measurement system.

اطلاعات بیشتر در مورد COI

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.
