利用紫外光作为辅助条件,在反胶束体系中采用一步双原位法合成了硝酸(HNO3)、对甲基苯磺酸(TSA)和5-磺基水杨酸(SSA)掺杂的银/聚苯胺(Ag/PANI)纳米复合材料.通过对复合材料进行红外光谱(FTIR)、紫外光谱(UV-Vis)、扫描电镜(SEM)、X射线衍射(XRD)和导电性能的测试,研究了不同质子酸对Ag/PANI纳米复合材料结构、形貌和导电性能的影响.测试结果表明,3种酸掺杂制备的Ag/PANI纳米复合材料均为聚苯胺包覆银粒子的核-壳结构.不同的质子酸掺杂会对Ag/PANI纳米复合材料的电性能有重要影响.在3种酸掺杂的复合材料中,TSA掺杂的复合材料的电导率最佳,为215.14 S·cm-1.
Using UV light as auxiliary condition, nitric acid (HNO3), p-toluenesulfonic acid (TSA) and 5-sulfosalicylic acid (SSA) doped silver were synthesized by one- / Polyaniline (Ag / PANI) nanocomposites were synthesized and characterized by FTIR, UV-Vis, SEM, XRD and conductivity testing The effects of different proton acids on the structure, morphology and electrical conductivity of Ag / PANI nanocomposites were investigated.The results showed that Ag / PANI nanocomposites prepared by three kinds of acid doping were the core-shell of polyaniline-coated silver particles Structure.The doping of different proton acids will have an important influence on the electrical properties of Ag / PANI nanocomposites.In the three kinds of acid-doped composites, the conductivity of TSA-doped composites is the best, 215.14 S · cm-1.
