摘要

采用化学氧化界面聚合法,以三氯化铁(FeCl_3·6H_2 O)为氧化剂,在二元非离子型表面活性剂介入下,于0℃制备特殊形貌的聚吡咯薄膜。研究了Span80/OP10复配体系对聚吡咯界面聚合成膜的影响,并利用红外光谱、扫描电子显微镜、循环伏安法以及循环寿命的测试对聚吡咯膜的性能进行了表征。结果表明,HLB值较低时,聚吡咯微观形貌表现为相互缠结交织在一起的无规线团状;随HLB值的增大,聚吡咯形貌变得均匀和蓬松,最终形成类似"囊泡"的结构;HLB值为8.0,添加的Span80浓度为1.23 g/L、OP10浓度为0.77 g/L时,制备的聚吡咯膜比电容值达169.21 F/g,经1 000次循环后,比电容值保留原来的84.5%,循环寿命较佳。
Polypyrrole(PPy) membranes with peculiar morphology were prepared via interfacial polymerization and assisted by binary non-ionic surfactant complex system at 0 ℃.The influence of sorbitan fatty acid(80) esters(SpanSO) and octylphenol polyoxyethylene(10) ether(OP10) complex system on obtained PPy films was investigated.The performances of PPy films were characterized by Fourier transform infrared(FT-IR) spectra,scanning electron microscopy(SEM),cycle voltammetry(CV) and cycle life tests.The SEM results presented that the PPy particles were entangled intertwined together to form a random coil-like structure at a low hydrophilic-lipophilic balance(HLB) value.PPy particles become uniform and fluffy with the increased HLB value,until formed similar structure of "vesicle" emerge.An optimized film specific capacitance was 169.21 F/g yielded at the HLB value 8.0and a stable cycle life which kept 84.5%of the first cycle after 1 000 cycles,the concentration of sorbitan fatty acid(80) esters(Span80) and octylphenol polyoxyethylene(10) ether(OP10) were 1.23 g/L and 0.77 g/L,respectively.
