摘要：　用固相合成法制备了纳米二氧化锰(nm MnO2),并通过原位聚合法制备了聚苯胺/纳米二氧化锰复合材料。研究结果表明:在苯胺/nm MnO2的盐酸反应体系中,nm MnO2可以使苯胺氧化聚合。在一定的nm MnO2用量下,聚苯胺的产率随苯胺添加量的增加而下降,nm MnO2在产物中的含量也随之下降,且含量很低。在苯胺/nm MnO2/过硫酸铵的反应体系中,研究了nm MnO2通过两种不同的加料方式原位制备PANI/nm MnO2复合材料的合成条件。第一种方式为nm MnO2和过硫酸铵同时与苯胺混合,一起参与苯胺的氧化聚合。第二种方法是先将过硫酸铵和苯胺混合,3min后再将nm MnO2加入反应体系中。研究表明:第一种加料方式得到的PANI/nm MnO2中nm MnO2的含量很低;第二种加料方式可以得到高nm MnO2含量(w=0.14～0.73)的产物,其电导率约10-4S/cm。
Nanometer Manganese dioxide (nm-MnO_2) was synthesized by solid-phase reaction. The polyaniline/nanometer manganese dioxide composite was prepared.It is shown that the polymerizaion of aniline could be carried out by the oxidation of nm-MnO_2 by in-situ polymerization. Both the yield of polyaniline and the content of nm-MnO_2 in the final product were decreased when aniline concentration increased at a fixed nm-MnO_2, the content of nm-MnO_2 in the product was founded very low. In the aniline/nm-MnO_2/ammonium peroxodisulfate (APS)/acid/water system, the in-situ synthesis conditions of polyaniline/nm-MnO_2 composite (PANI/nm-MnO_2) were studied by two different feeding methods of nm-MnO_2 into the reaction system. The first method is that nm-MnO_2 and APS was mixed together with aniline at the same time. The second method is that nm-MnO_2 was put into system after three minutes of mixing the acidic aqueous solution of APS and aniline. The results indicate that PANI is main component and the content of nm-MnO_2 is very low in the PANI/nm-MnO_2 composite obtained by the first synthesis method. By using the second feeding method PANI/nm-MnO_2 conductive composite with the higher nm-MnO_2 content (0.14-0.73) and conductivity (10^(-4) S/cm) could be prepared.
