摘要
研究制备了SiO_2-PVDF阳、阴离子交换膜,并确定了最佳的制备条件:聚偏氟乙烯(PVDF)的添加量与单体甲基丙烯酸缩水甘油酯(GMA)和交联剂二乙烯苯(DVB)总量比为2∶1,纳米二氧化硅添加量为0.10%,对阳、阴离子交换膜而言,DVB添加量分别为GMA的4%和5%。将制备的SiO_2-PVDF阳、阴离子交换膜利用热压成型法制得SiO_2-PVDF双极膜。最佳的热压温度为190℃,最佳的热压压力为10 MPa。
SiO2-PVDF cation and anion exchange membranes were prepared respectively. And the optimal preparation conditions were determined, which were as follows： the ratio of polyvinylidene fluoride（ PVDF） to the mixture mass of glycidyl methacrylate（ GMA） and divinyl benzene（ DVB） was 2∶ 1,the addition amount of SiO2 was 0. 10% of the total weight,and for the cation and anion exchange membrane,the amount of crosslinking agent DVB was 4% and 5% of GMA,respectively. Then the SiO2-PVDF cation and anion exchange membranes were used to prepare bipolar membrane（ BPM） by hot-pressing approach. The optimal hot-pressing temperature was 190 ℃ and optimal hot-pressing pressure was 10 MPa.
