摘要
首先以纳米凹凸棒石(ATP)为核体,盐酸为一次掺杂剂,原位合成盐酸掺杂聚苯胺/凹凸棒石纳米复合材料(HCl-PANI/ATP),然后在氨水溶液中脱杂,再以磺基水杨酸(SSA)为二次掺杂剂,制备了磺基水杨酸掺杂聚苯胺/凹凸棒石纳米复合材料(SSA(HCl)-PANI/ATP)。利用热分析(TG-DTA),傅立叶红外光谱(FTIR),X-射线衍射(XRD),粒度分布和电导率测试等手段对产物进行了结构表征和性能研究。结果表明,与HCl-PANI/ATP相比,二次掺杂将复合材料的体积电阻率从10Ω·cm降到2Ω·cm,导电稳定性从90℃提高到120℃,平均粒径从383.8nm降到261.6nm;与传统掺杂工艺相比较,SSA的使用量大约降低了33.3%。
Nanocompositie of polyaniline/attapulgite doped with hydrochloric acid(HCl-PANI/ATP) was in-situ synthesised by using attapulgite(ATP) as nuclear body at first,then dedoped in the ammonia solution,and nanocompositie of polyaniline/attapulgite doped with sulfosalicylic acid(SSA(HCl)-PANI/ATP) was prepared by the secondary doping process.The prepared samples were researched by thermogravimetry(TG),differential thermal analysis(DTA),Fourier transform infrared spectra(FTIR),X-ray diffraction(XRD),particle size analyzer and electrical conductivity tests respectively.The results showed that the volume resistivity of SSA(HCl)-PANI/ATP decreased from 10 Ω·cm to 2 Ω·cm,its conducting stability increased from 90℃ to 120℃,its average size dropped from 383.6 nm to 261.6 nm in comparison with HCl-PANI/ATP.Compared with the traditional doping method,the amount of SSA could reduce about 33.3%.
