چکیده
در این پژوهش، از روش نوین کندوپاش پلاسمایی برای لایه‌نشانی مس بر فیلم فیبروین ابریشم استفاده شده است. به دلیل خواص منحصر به فرد فیبروین ابریشم از جمله انعطاف‌پذیری بالا، خواص مکانیکی خوب و سازگاری با بدن، می‌توان از فیبروین رسانا به عنوان نسل آیندهی مواد الکترونیکی انعطاف‌پذیر، البسههای رسانا و مواد کاشتنی داخل بدن استفاده کرد. در این کار، سطح فیلم فیبروین به مدت 6 دقیقه توسط سیستم کند و پاش پلاسمایی بهینه شده، با مس لایه‌نشانی شده است. تست رسانایی فیلم فیبروین و نتایج رسانایی جهارپروب نشان می‌دهد که فیلم فیبروین ابریشم پس از لایه‌نشانی، خاصیت رسانایی خوبی پیدا کرده است. آنالیز میکروسکوپ الکترونی روبشی، بافت سطح و چگونگی قرارگیری اتمهای مس مابین اجزای روی سطح را به وضوح نشان می‌دهد. هم‌چنین، از انالیز EDX نیز درصد اتمهای مس لایه‌نشانی شده نشان داده شده است. نتایج به دست آمده نشان می‌دهد که روش کند و پاش پلاسمایی یک روش سریع، پاک و کارآمد جهت لایه‌نشانی فلز روی سطوح پلیمری مانند فیبروین و تولید پلیمرهای رسانای انعطاف‌پذیر می‌باشد.

چکیده [English]
In this work, the plasma sputtering technique was used for Cu deposition on the silk fibroin film. Because of the extraordinary properties of silk fibroin such as flexibility, excellent mechanical properties, and biocompatibility, it is considered a promising material for the new generation of flexible electronic devices, implants, and wearable electronic devices. After optimization of magnetron sputtering parameters, silk fibroin film was deposited by Cu as a sputtering target for 6 minutes. The results of conductivity analyses and tests of four probes demonstrated that the deposition of silk fibroin film by plasma sputtering results in conductive film fabrication. Moreover, the surface morphology was examined by SEM analysis which clearly shows the Cu atoms among species on the surface. EDX analyses revealed the elemental composition of the material which shows clear Cu peaks after plasma sputtering. As a result, plasma sputtering is a fast, clean, and efficient technique for the deposition of metal on polymer surfaces including silk fibroin to form a conductive flexible surface.
