采用超声化学法,在没有任何模版的条件下合成了产物纯净、尺寸单一的纳米棒状聚苯胺,采用SEM、XRD、TG和BET等方法对产物进行了表征.研究表明,氧化剂过硫酸铵的用量与产率存在较大关联,氧化剂和苯胺单体的物质的量比1∶1时可以达到最大产率;盐酸浓度对产物形貌有较大影响,只有盐酸浓度达到一定程度才可以得到纳米棒状聚苯胺;超声化学法合成的聚苯胺比表面积要大大高于市售和机械搅拌法合成的聚苯胺,比表面积可达29.5m~2/g.
Pure polyaniline which shape is nano-stick is synthesized via sono-chemical without any surfactant activity and it was characterized by SEM, XRD, TG, BET, et al. The oxidant dosage play a key role in the produciton to material ratio and the best ratio of oxidant to anliline shape. The specific surface area of polyanline which is fabricated by sono-chemical is bigger than the specific surface area of polyanline is bought or is synthesized via other approaches and it is 29.5m~2/g.
