In this study, carbon material similar to graphene structure (GLS) was prepared from graphite and the carbonization of Turkish human hair fibers (HHC) and utilized for the modification of electrode to evaluate the supercapacitance performance. Electrochemical characterization of the HHC-based GLS (HHC-GLS) modified electrodes have been carried out with cyclic voltammetry and electrochemical impedance spectroscopy. The morphology and chemical composition of the resultant GLSs were characterized by scanning electron microscopy, X-Ray diffraction spectroscopy, Raman and Fourier Transform infrared spectroscopy analysis. HHC-GLS displayed a good electrochemical activity than the graphite sourced graphene and possess very similar morphological properties with commercial graphene. Carbonization of the waste hair was carried out at 280°C to improve the pore structure as the first step of GLS synthesis. HHC-GLS modified electrode exhibited the best electrochemical activity and utilized as a charge storage device. The best specific capacitance value was found to be 139.00 F g⁻¹ in 6.00 M KOH_(aq) at a scan rate of 100.00 mV s⁻¹ and good stability over 500 cycles. Whereas an energy density of 19.3 Wh kg⁻¹ and power density of 6.95 kW kg⁻¹ were obtained from the electrode when operated in the voltage range from −1.00 to 0.00 V. This work offers a new approach to human hair waste management in terms of promising green energy applications.

在这项研究中，由石墨和土耳其人发纤维（HHC）的碳化制备了类似于石墨烯结构（GLS）的碳材料，并将其用于电极的改性以评估超电容性能。基于HHC的GLS（HHC-GLS）修饰电极的电化学特性已通过循环伏安法和电化学阻抗谱进行了表征。通过扫描电子显微镜，X射线衍射光谱，拉曼和傅立叶变换红外光谱分析来表征所得GLS的形态和化学组成。HHC-GLS显示出比石墨来源的石墨烯更好的电化学活性，并且具有与商业石墨烯非常相似的形态学特性。作为GLS合成的第一步，废毛的碳化在280℃下进行以改善孔结构。HHC-GLS修饰电极表现出最佳的电化学活性，并用作电荷存储设备。发现最佳比电容值为139.00 F g^-1在6.00中号KOH _{（水溶液）}以100.00毫伏s的扫描速率^-1和良好的稳定性超过500个循环。当在-1.00至0.00 V的电压范围内操作时，电极的能量密度为19.3 Wh kg ^-1，功率密度为6.95 kW kg ^-1。这项工作为人发废物管理提供了一种新方法有前景的绿色能源应用。该研究已获得土耳其专利商标局的专利（土耳其专利局申请号：（2019/22841））。
