%X 在复杂电磁干扰环境中提供增强的电化学储能性能对于稳定高效的集成电路和系统具有重要的研究意义。通过激光诱导石墨烯(LIG)技术在含碳聚合物上的二次扫描制备了四氧化三铁原位修饰多孔石墨烯复合材料(LIG/Fe<sub>3</sub>O<sub>4</sub>)。控制FeCl<sub>3</sub>溶液的浓度可以显著影响Fe<sub>3</sub>O<sub>4</sub>纳米颗粒的数量和尺寸，因此可以有效调控复合材料的理化性能。此外，对不同浓度合成的LIG/Fe<sub>3</sub>O<sub>4</sub>材料进行了形貌结构和理化性质分析，结果表明，当FeCl<sub>3</sub>浓度为0.6 mol/L时，复合材料的电化学和储能性能最佳，在1 mv？s<sup>？</sup><sup>1</sup>扫速下表现出较高的面积电容(617.5 mF/cm<sup>2</sup>)，约为LIG的10倍。LIG/Fe<sub>3</sub>O<sub>4</sub>还具有21.2 emu/g的最高饱和磁化强度和1132.2 S/m的出色电导率，因此可以扩展到2.6~8.2 GHz的电磁屏蔽应用。<br />
Enhancing electrochemical energy storage performance in complex electromagnetic interference environments holds significant research importance for stable and efficient integrated circuits and systems. In this study, Fe<sub>3</sub>O<sub>4</sub> In-situ modified porous graphene composites were prepared by double laser-induced pyrolysis of graphene on carbon-containing polymer. Controlling the concentration of FeCl<sub>3</sub> can significantly affect the quantity and size of Fe<sub>3</sub>O<sub>4</sub> nanoparticles, so the physicochemical properties of the composite can be effectively regulated. Furthermore, morphological structure and physicochemical property analyses were conducted on LIG/Fe<sub>3</sub>O<sub>4</sub> materials synthesized with different concentrations. The results indicate that composite material exhibited optimal electrochemical and energy storage performance when FeCl<sub>3</sub> concentration was 0.6 mol/L, demonstrating a high specific capacitance (617.5 mF/cm<sup>2</sup>) at a scan rate of 1 mV？s<sup>？</sup><sup>1</sup>, approximately 10 times that of LIG. The LIG/Fe<sub>3</sub>O<sub>4</sub> composite also displayed a remarkable maximum saturation magnetization of 21.2 emu/g and outstanding electrical conductivity of 1132.2 S/m, enabling its application for electromagnetic shielding in the frequency range of 2.6~8.2 GHz.
