采用苯胺，过（二）硫酸铵(NH4)2S2O8、硝酸银AgNO3、甲醛、十二烷基苯磺酸钠等为原料，合成了银-DBSA掺杂的聚苯胺。最佳合成的具体条件：反应温度在0～5℃下，苯胺、(NH4)2S2O8和十二烷基本磺酸钠摩尔比为4：4：1,加入的AgNO3的物质的量为苯胺的10%，反应4.5小时后，再加适量的甲醛还原得到银-DBSA掺杂聚苯胺。样品的IR光谱表明，通过还原后峰型和峰位都发生了明显的变化。样品的XRD分析知,银-DBSA掺杂聚苯胺有很强的金属元素银的峰,样品的SEM表明,还原得到的银-DBSA掺杂聚苯胺的颗粒度更小，且有许多银白色的银粒分散在高聚物大分子中。样品的TG热分析表明，银-DBSA掺杂聚苯胺在420℃以下是很稳定的，说明掺入银后的聚苯胺的热稳定性得到了显著的增强。用四探针电阻仪测试样品的电导率约为14S/cm，因此它是很有希望用于全印制电路技术的新材料。

This paper introduces polyaniline, (NH4)2S2O8, AgNO3, formaldehyde, sodium and other raw materials, as well as synthesis of silver-DBSA doped polyaniline. Best synthesis of the specific conditions is:reaction temperature at room temperature. The molar ratio of aniline, (NH4)2S2O8 and sodium dodecyl is 4:4:1, The mole rate of doping AgNO3 is 10%compared with aniline. After agitating 4.5 hours, doping an appropriate amount of formaldehyde into the solution, we have silver-DBSA doped polyaniline. IR spectra of samples showed that signiifcant changes have taken place that appearance and position of peak of samples. The XRD analysis of samples showed that silver-DBSA doped polyaniline has a strong peak of silver metal elements. SEM samples showed that particle size of silver-DBSA doped polyaniline smaller than AgNO3-DBSA doped polyaniline, and there are many silver-white silver particles dispersed in polymer macromolecules. TG thermal analysis of samples show that the silver-DBSA doped polyaniline is stable under 420℃, it indicated good thermal stability of synthetic products. The conductivity of samples that tested by four-probes conducting instrument is about 14 s/cm. So the silver-DBSA doped polyaniline is a promising new material. It was uesed in all printed cicurit and other aspects.
