摘 要:以聚醚砜(PES)为原料,采用氯磺酸(CSA)为磺化剂,通过控制反应温度和时间制备系列磺化聚砜(SPES),并以SPES为基质,二维黑磷(BP)为功能填料,采用溶液铸膜法制备了复合质子交换膜。采用红外光谱分析仪(FTIR)、X射线衍射仪(XRD)、扫描电子显微镜(SEM)等对材料结构进行表征,研究了复合膜的吸水率、质子交换性、阻醇性等。结果表明,SPES的磺化度随反应温度、时间、磺化剂浓度的升高而增大。BP的添加增强了复合膜的热稳定性、氧化稳定性、质子交换性、阻醇性等综合性能。在相同测试条件下SPES基膜的甲醇渗透率为1.185×10^(-6)cm^(2)/s,而5%(质量分数,下同)SPES/BP复合膜的甲醇渗透率仅为2.88×10^(-7)cm^(2)/s。A series of sulfonated polysulfone(SPES)was prepared through controlling the reaction temperature and time with polyethersulfone as a raw material and chlorosulfonic acid as a sulfonating agent.Further,proton exchange membrane composites were fabricated through solution casting using 2D black phosphorus as a functional filler and SPES as a matrix.The structures of the as-prepared materials were characterized by Fourier transform infrared spectrometer,Xray diffractometer,and scanning electron microscope,and their properties in terms of water absorption,proton exchange and alcohol resistance were studied.The results indicated that the sulfonation degree of SPES increased with increasing the reaction temperature,time,and sulfonation agent concentration.The addition of black phosphorus enhanced the comprehensive properties of the composite membranes,which included thermal stability,oxidation stability,proton exchange ability,and alcohol resistance.Under the same test conditions,the SPES substrate membrane exhibited a methanol permeability of 1.185×10^(-6) cm^(2)/s,whereas the SPES/BP composite membrane containing 5%BP only present a methanol permeability of 2.88×10^(-7) cm^(2)/s.
