聚苯胺/纳米二氧化锰复合材料Ⅱ.形貌表征
Polyaniline/Nanometer Manganese Dioxide Composite Ⅱ.Structure Characterization
-
摘要: 通过先用过硫酸铵引发苯胺的聚合，然后再将纳米二氧化锰(nm-MnO2)加入过硫酸铵和苯胺的反应体系中。原住制备了导电聚苯胺／纳米二氧化锰复合材料(PANL／nm-MnO2)，并有效地避免了nm-MnO2在苯胺氧化聚合中的消耗。扫描电镜和透射电镜显示复合材料中nm-MnO2为聚苯胺所包裹。X射线衍射研究表明，在复合材料制备过程中nm-MnO2的晶型未发生变化，在复合材料中聚苯胺为非晶相结构。Abstract: The conducting polyaniline/nanometer manganese dioxide composite (PANI/nm-MnO_2) was synthesized via in-situ technique by controlling the time of feeding the nm-MnO_2 in the polymerization system of ammonium peroxodisulfate and aniline. The time is 3 min
