چکیده
در این پژوهش، خواص الکتریکی و مکانیکی ورق‌ انعطاف‌پذیر پلی‌اورتان-گرافن (P/G) بررسی شد. نتایج نشان می‌دهد که افزودن گرافن (G) منجر به ایجاد مسیرهای رسانا در بستر پلیمر می‌شود. با افزایش کسر جرمی G در ترکیب، مدول یانگ افزایش واستحکام کششی کاهش می‌یابد. P/G با 5 درصد وزنی گرافن، مقاومت بالایی در محدوده پوست انسان از خود نشان می‌دهد که کرنش کششی خوبی نیز دارد (154٪). همچنین، افزون بر مقاومت ورق خوب P/G با 20 درصد وزنی (135 اهم بر مربع)، تغییرات نسبی مقاومت به عنوان تابعی از زاویه خمش و کشش اندازه گیری شد و نتایج نشان می‌دهد که برگشت‌پذیری و قابلیت‌ خوبی به عنوان کاربردهای الکترونیکی پوشیدنی و حسگر کرنش دارد.

چکیده English

In this research the electrical and mechanical properties of the flexible polyurethane-graphene (P / G) composite films were investigated. The results show that the addition of graphene (G) leads to making the conductive paths in the polymer matrix. By increasing the mass fraction of G in composition, Young’s modulus increases, as well as the tensile strength decreases. P/G with 5wt% exhibits a high sheet resistance about the human skin range, which has a good tensile strain (154%). Besides the good sheet resistance of P/G with 20wt% of G (135 Ω/sq), the relative differentiation of resistance as a function of bending angle and tensile is determined, and the results show strong reversibility and capabilities as wearable electronics and strain sensing applications.
