چکیده

Conducting polymer/single-wall carbon nanotubes (SWNTs) composites were synthesized by the in situ chemical oxidative polymerization method. Thiophene (Th) and 2-(2-Thienyl) Pyrrole (TP) is selected as the interfacial modifier for SWNT–Poly(Th-TP) nanocomposite. The resulting cablelike morphology of the composite SWNT–Poly(Th-TP) structures was characterized with Fourier transform infrared, ultraviolet–visible spectroscopy, field emission scanning electron microscopy, thermogravimetric analysis, X-ray diffraction, and transmission electron microscopy. The standard four-point-probe method was used to measure the conductivity of the samples. Field emission scanning electron microscopy and transmission electron microscopy analysis revealed that the SWNT–Poly(Th-TP) composites were core (SWNTs) and shell Poly(Th-TP) hybrid structures. Spectroscopic analysis data for the composites were almost identical to those for Poly(Th-TP), supporting the idea that SWNTsserved as templates in the formation of a coaxial nanostructure for the composites. The physical properties of the composites were measured and also showed that the SWNTs were modified by conducting Poly(Th-TP) with an enhancement of various properties.

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.
