Crustacean cuticles are receiving extensive attention for its potential in developing environmentally friendly and high energy density electrodes for supercapacitor applications. In the current work, the demineralized tergite cuticle of mantis shrimp was employed as a precursor for the fabrication porous biochar. The structural benefits of the cuticle, including the hierarchical nanofiber networks, and the interpenetrating pore systems were maximumly retained, providing a high carbon content and specific surface area scaffold. Graphene oxide sheets were deposited across the biochar through the pore canal systems to further increase the conductivity of the biochar, forming a novel freestanding carbon composite. Throughout the modification process, the material products were examined by a range of methods, which showed desired structural, chemical and functional properties. Our work demonstrates that high performance carbon materials can be manufactured using a simple and green process to realize the great potential in energy storage applications.
甲壳动物的角质层因其在开发用于超级电容器的环境友好型和高能量密度电极方面的潜力而受到广泛关注。在当前的工作中，螳螂虾的脱矿化背板角质层被用作制备多孔生物炭的前驱体。角质层的结构优势，包括分级纳米纤维网络和互穿孔隙系统，被最大程度地保留下来，提供了一个高碳含量和比表面积的支架。氧化石墨烯片通过孔隙通道系统沉积在生物炭上，以进一步提高生物炭的导电性，形成一种新型的独立碳复合材料。在整个改性过程中，通过一系列方法对材料产品进行了检测，结果表明其具有理想的结构、化学和功能特性。我们的工作表明，可以使用简单且绿色的工艺制造高性能碳材料，以实现其在储能应用中的巨大潜力。
