摘要: 利用表面活性剂对阳极氧化铝(AAO)模板进行化学修饰,发展了模板合成法,从而得到更小尺寸的聚苯胺纳米管、线.在表面活性剂十八烷基脂肪酸(R18)修饰下,在14 nm孔径的AAO模板中合成7 nm的纳米线.对不同表面活性剂的比较后发现,通过改变修饰表面活性剂上烷基链长可以对所制备的聚合物纳米管、线的直径进行调控.

关键词: 模板的化学修饰,  AAO模板,  小尺寸聚合物纳米线

Abstract: A novel strategy has been developed to fabricate PANI nanowires or nanotubes with smaller diameter in AAO template by chemical modification of selected surfactants. With the assistance of surfactant octadecanoic acid (R18), we got the PANI nanowires which diameter is 7 nm in AAO pores with a diameter of 14 nm. By comparing different surfactants, we concluded that by assembling selected surfactant with different length alky group to AAO templates, the diameters of polymer nanowires or nanotubes could be controlled.

Key words: Chemical modification of template,  AAO template,  Small-scale polymer nanowires
