聚苯胺/磺化酞菁铜自组装复合薄膜的制备与表征

Preparation and characterization of PANI/CuTsPc composite thin films by layer-by-layer self-assembly

运用层层自组装的技术制备了聚苯胺/磺化酞菁铜(PANI/CuTsPc)超分子复合薄膜,并通过紫外-可见-近红外吸收光谱、傅立叶红外光谱、X射线衍射仪与原子力显微镜对薄膜进行了表征与分析。紫外-可见-近红外吸收光谱表明,PANI和CuTsPc具有良好的层层自组装特性,沉积过程具有均匀性与重复性;傅立叶红外光谱表明,复合薄膜是由PANI和CuTsPc组成的,PANI和CuTsPc通过静电力的作用组装成膜;X射线衍射结果表明,复合薄膜是非晶态的;原子力显微镜观察到薄膜表面是比较均匀和致密的,但有一定的粗糙度。

Polyaniline/Copper（II） phthalocyanine-tetrasulfonic acid tetrasodium salt（PANI/CuTsPc） supramolecular composite thin films were prepared by the technique of laye-by-layer self-assembly, and their structures and properties were characterized by UV-VIS-NIR, FT-IR, XRD and AFM. The UV-VIS-NIR absorption spectra indicated that not only PANI and CuTsPe had good characteristic of layer-by-layer self-assembly, but also the deposit process was uniform and repetitive; the results of FT-IR showed that PANI and CuTsPc were successfully assembled on the films by electrostatic adsorb force; the XRD analyses showed that composite thin films were of non-crystallinity; the AFM image showed that the surface of thin films were relatively homogeneous and compact, but the surface was a little rough.
