Graphene-based membranes have been explored in different energy and environmental applications. The 2D nanochannel structure and low frictional water flow inside micrometer-thick graphene oxide (GO) laminates make them attractive candidates for large-scale energy storage systems. Through the design of large size differences between charge carriers and redox species, GO membranes can achieve high rejection and high ionic conductivity in various solutions. Furthermore, tailoring the degree of oxidation or using bacterial cellulose as the hybrid component shows the flexibility to tune the microstructure and ionic transport of GO-based membranes. As a separator, GO membranes can achieve a rejection of >95% for a number of active species, and the ionic conductivity can reach 1.7 × 10⁻² S cm⁻¹ in 1 M H₂SO₄ electrolytes. Redox flow batteries with GO-based separators show a charge-discharge profile similar to that of commercial Nafion 212 and achieve a stable cycling performance with a high Coulombic efficiency of ∼98%.

基于石墨烯的膜已在不同的能源和环境应用中得到了探索。微米级氧化石墨烯（GO）层压板内部的2D纳米通道结构和低摩擦水流使其成为大规模储能系统的有吸引力的候选材料。通过设计载流子和氧化还原物质之间的大尺寸差异，GO膜可以在各种溶液中实现高排斥性和高离子电导率。此外，调整氧化程度或使用细菌纤维素作为杂化组分显示出灵活性，可以调节基于GO的膜的微观结构和离子迁移。作为隔膜，GO膜可对许多活性物质实现大于95％的截留率，离子电导率可达到1.7×10 ^-2 S cm ^-1在1 MH ₂ SO ₄电解液中。具有基于GO的隔板的氧化还原液流电池显示出与商用Nafion 212相似的充放电曲线，并实现了稳定的循环性能和高达98％的库仑效率。
