چکیده

 لایه برداری الکتروشیمیایی از گرافیت، یکی از روش‌های سنتز گرافن بوده و علی رغم اینکه توان سل الکتروشیمیایی در این فرایند می‌تواند نقشی اساسی ایفا کند، کمتر مورد توجه قرار گرفته‌ و پژوهش‌های قبلی در بازه‌ای محدود از اختلاف پتانسیل یا جریان الکتریکی انجام شده است. در این پژوهش تاثیر توان بر مقدار گرافن لایه‌برداری شده و مقدار گروه عاملی قرار گرفته روی آن ها در بازه‌ای گسترده بررسی شده است. از آنالیزهایی نظیر رسانایی، توزین، جذب مرئی-فرابنفش و میکروسکوپ الکترونی عبوری برای تعیین مشخصات محصولات استفاده شد. بر اساس نتایج با کاهش توان ورودی به سل، لایه‌برداری از الکترود بیشتر شده و مقدار گروه عاملی آن‌ها نیز بیشتر می‌شود.

چکیده [English]

The electrochemical exfoliation of graphite is a method to obtain graphene. Despite the important role of electrical power in this process, it hasn’t been investigated extensively. In this research, the effect of electrical power in an extensive range on the amount of exfoliated graphene and oxygen functional groups was studied. Transmission electron microscopy, weighing, UV-vis spectroscopy and electrical conductivity were used for characterization of the products. According to the results, by decreasing the power, the amount of exfoliated graphene and its functional groups increased.
