چکیده

In this research, a cost-effective piezoresistive sensor based on polyvinyl chloride/reduced graphene oxide (PVC/rGO) was fabricated and its performance was investigated. Composites were prepared by adding ۰.۱-۳۰ wt.% of rGO to the PVC matrix followed by solution casting. The plot of electrical conduction-concentration was constructed to obtain the percolation threshold concentration. It was found that the percolation threshold of reduced graphene oxide leading to a continuous stable electrical conductivity in PVC matrix is about۲۵% beyond which electrical resistance was reduced drastically from some ۸۰۰GΩ to lower than۱۰۰KΩ range The relative change in electrical resistance of prepared polymer parts as a result of pressure (stress), strain, torsion and low strength impact was studied. The results showed that the fabricated composite can be used for sensing and/or monitoring and measurement of any mechanical displacement with high sensitivity, promising reproducibility and satisfactory durability.

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.
