交流扩孔对铝氧化膜电解着色的影响

研究了磷酸溶液交流扩孔对铝阳极氧化膜电解着色的影响。结果表明,磷酸交流扩孔后氧化膜的电解着色性能发生了明显变化。改变交流扩孔的工艺条件,可获得黄色、灰色、绿色、古铜色、蓝色等多种色调的氧化膜。扫描电镜照片显示,经磷酸溶液交流扩孔后,多孔氧化膜孔径可增大一倍以上,电解着色并未引起膜表面微观形貌的明显变化。所得最佳扩孔工艺条件为:磷酸90~110g/L,电流密度1.5~1.75A/dm2,电压5~10V,时间8~12min,温度20~30°C。     

Effects of synthetic conditions of pulse galvanostatic method on electroactivity of polyaniline

1　INTRODUCTIONConducting polymers, due to their potentialapplication prospects, have been investigated ex tensively during the past decade[1 10]. Conductingpolyaniline (PANI), on account of its excellent op tical and electronic properties, is promising inmany fields, such as electronic devices, electro chromic devices, and ion switching devices[11 16].The morphology of conductive PANI can varygreatly with the preparation methods and condi tions.
