PPy@In-BDC复合材料的制备与表征

Preparation and Characterization of the PPy@In-BDC Composite Material

通过碘氧化法,在金属有机框架材料In-BDC(BDC2-为对苯二甲酸酸酐)的一维孔道内实现吡咯的化学氧化聚合,得到了PPy@In-BDC复合材料。利用X射线粉末衍射、扫面电子显微镜、热失重、红外光谱、N_2吸附以及四探针法表征了制备过程中所得材料的结构、组成及性能。压片成型后,PPy@In-BDC复合材料的电导率达10^(-5) S/cm,和无模板法合成的块状聚吡咯(～10^(-8) S/cm)及模板In-BDC相比,至少有3个数量级的提高。

In the 1D channels of the In-BDC,polypyrrole could be synthesised by iodine oxidation,and then the PPy@In-BDC composite material was achieved.The structure,composition and properties of the obtained materials were characterized by PXRD,SEM,TG,IR,N_2 adsorption and four-probe method.The electronic conductivity of PPy@In-BDC composite material after molded was 10^（-5） S/cm,which had an increment of at least three orders of magnitude,compared with the bulk PPy（—10^（-8） S/cm）and In-BDC template.
