以含金属元素的大分子为原料，制备了性能上级的羧甲基纤维素（CMC）-壳聚糖（CS）双极膜（BPM）。用酞菁铜16-羧酸（CuPc（COOH）16）对羧甲基纤维素阳离子层进行改性，以提高其离子交换容量和阳离子转移速率，促进中间层的水分解。壳聚糖与乙酰基二茂铁交联制备阴离子层。采用浇注法制备了改性后的BPM，其物理化学性能优良。为了改善阴离子交换层和阳离子交换层的相容性，将聚乙二醇（PEG）与CMC和CS共混。扫描电子显微镜（SEM）图像示出了由彼此紧密结合的阴离子层和阳离子层组成的结构。溶胀结果表明，BPM在[OH-]≤10 mol·L-1的碱性溶液中具有良好的亲水性和形状稳定性。热重分析结果表明，改性后的BPM具有良好的热稳定性。与未改性的BPM相比，其交流阻抗和工作电压均大幅降低。此外，改性后的BPM具有更高的离子渗透性，这有利于其广泛的应用。
A bipolar membrane (BPM) of carboxymethyl cellulose (CMC) and chitosan (CS) with superior performance was prepared based on the macromolecules containing metal elements. A carboxymethyl cellulose cation layer was modified by copper phthalocyanine 16-carboxylic acid (CuPc(COOH)16) to improve its ion exchange capacity as well as cation transfer rate and promote water splitting at the intermediate layer. Chitosan was crosslinked with acetyl ferrocene to prepare the anion layer. A casting method was used to prepare the BPM which showed excellent physical and chemical properties after modification. To improve the compatibility of the anion-exchange layer and cation-exchange layer, polyethylene glycol (PEG) was blended with both the CMC and CS. Scanning electron microscopy (SEM) images illustrated a structure that consisted of an anion layer and a cation layer that were closely combined with each other. The swelling results implied a proper hydrophilic performance and good shape stability in an alkali solution ([OH−]≤10 mol·L−1) of the BPM. After modification, the BPM with the metal elements exhibited good thermal stability, as shown by the thermogravimetry (TG) results. Compared with the BPM that was unmodified, both the AC impedance and the working voltage were decreased sharply. Furthermore, the modified BPM exhibited higher ion penetrability which is beneficial for its wide application.
