近日，实验室彭龙同学、朱宇灿老师成功开发了一项不仅制备简单还显著提高了电化学储能的技术，证明了选择性吸附自组装策略在制备分子改性石墨烯薄膜（M-GF）中的巨大潜力。成功证明了选择性吸附自组装策略制备的M-GF比传统的物理混合方法具有更高的性能。这些新型M-GF具备活性有机分子支持的三维多孔结构，其层间间距均匀加宽，这一研究成果彰显了采用选择性吸附自组装策略的M-GF在电化学储能领域的潜在应用，并有望成为高性能电极材料的新选择。

Molecular modified graphene films (M-GFs) have the advantages of simple preparation and high electrochemical activity, which has a promising future in the field of electrochemical energy storage. However, the influence of molecular doping technology is rarely studied for electrochemical performance of the M-GFs, hindering the development of high-performance M-GFs. Herein, we have demonstrated that a selective adsorption self assembly strategy can prepare M-GFs with higher performance than physical mixing method. The prepared M-GF exhibits a three-dimensional porous structure with active organic molecules support, and its interlayer spacing is evenly widened. The resulting M-GFs as cathode material of aqueous Zinc-ion hybrid supercapacitors (AZISCs) exhibits a high specific capacitance of 228F g^-1, and a good capacitance retention of 42% (@10 A g^-1),  which are 25% and 13% higher than those of the physical mixing method, respectively. Besides, the energy and power density of the devices can reach 82 Wh kg^-1 and 20.3 kW kg^-1, respectively. After 5000 cycles of charge and discharge testing, the capacitance retention rate of the device can still reach 94%. The impressive results indicate that the M-GFs by selective adsorption self-assembly strategy could be a potential high-performance electrode material for the AZISCs.
