摘　　要：磺化聚醚醚酮(SPEEK)可作为钒液流电池(VFB)的质子交换膜,但替代现有商用Nafion膜,仍需要进一步改进。与常见无机填料相比,功能化碳基纳米材料能够保持SPEEK膜原本的质子传输结构、稳定性及力学性能,并进一步提高SPEEK膜的性能。文章综述功能化碳基纳米材料,如氧化石墨烯(GO)、多壁碳纳米管(MWCNTs)、碳颗粒以及碳氮化合物等,用于填充VFB用SPEEK质子交换膜的研究进展。研究表明:功能化碳基纳米材料能够改善SPEEK膜对钒离子的渗透性、选择性,使SPEEK膜的稳定性、力学性能和使用寿命也略有增加。碳基纳米材料改性SPEEK膜可替代商用Nafion膜。Sulfonated poly(ether ether ketone)(SPEEK)can be used as proton exchange membrane of vanadium flow battery(VFB),but it still needs further improvement to replace the existing commercial Nafion membrane.Compared with common inorganic fillers,functional carbon-based nanomaterials can maintain the original proton transfer structure,stability and mechanical properties of SPEEK membrane,and further improve the performance of SPEEK membrane.The research progress of functional carbon-based nanomaterials,such as graphene oxide(GO),multi-walled carbon nanotubes(MWCNTs),carbon particles and carbon nitrides,used for filling SPEEK proton exchange membranes for VFB is reviewed.The results show that functional carbon-based nanomaterials can improve the permeability and selectivity of SPEEK membrane to vanadium ions,and slightly increase the stability,mechanical properties and service life of SPEEK membrane.Carbon-based nanomaterials modified SPEEK membrane can replace commercial Nafion membrane.
