摘要:
实验以过氧化苯甲酰（BPO）为引发剂，在聚偏氟乙烯（PVDF）分子链上接枝对苯乙烯磺酸钠（SSS）的同时掺杂二氧化硅(SiO2)颗粒，进而得到复合离子交换膜(PVDF/xSiO2-g-PSSA).通过傅里叶红外分光光度计（FT-IR）、X射线衍射仪（XRD）和耗散型石英晶体微天平（QCM-D）分析了膜的化学组成、结晶形态和抗污染性，并考察不同SiO2添加量对膜的亲水性和电导率性质的影响.结果表明：添加SiO2使膜的亲水性能显著提高，电导率略微下降.通过QCM-D测试发现，亲水性材料SiO2的加入，使膜表面污染物的吸附量下降，抗污染性增强，有利于提高微生物燃料电池(MFCs)在长期运行中的稳定性
Abstract:
In this investigation, benzoyl peroxide (BPO) was used as an initiator, concurrently, silica (SiO2) was doped on the molecular chain of the polyvinylidene fluoride (PVDF) coupled with sodium styrene sulfonate（SSS). After that, the composite proton exchange membrane (PVDF/xSiO2 -g-PSSA) could be obtained. Chemistry constitution, crystal morphology and antipollution were analyzed by fourier transform infrared spectrophotometer (FT -IR), x-ray diffractometer (XRD) and quartz crystal microbalance (QCM -D). At the same time, the effects of different SiO2 concentration on the hydrophily and conductivity of membrane were investigated . The results showed that the hydrophilic property could be significantly improved and conductivity fell slightly by adding SiO2 . The QCM -D tests show that adding SiO2 decreased adsorption quantity of pollutants on the surface of membrane and improved antipollution, which presented a potential favorable application in the fuel cell
