摘要
以对苯二胺(p-PDA)为单体,氯金酸(HAuCl4)为氧化剂和Au源,氧化石墨烯(GO)为基底,通过原位聚合伴随Au纳米粒子生成的方法获得了聚苯胺/石墨烯/金(PpPD/GO/Au)的纳米复合材料。FESEM、FT-IR、XRD等测试表明,聚苯胺类衍生物、氧化石墨烯以及金纳米粒子三相在整个纳米复合材料中共存。材料的复合使得体系同纯PpPD与GO相比,热稳定性得到大幅度提高。电化学测试表明,相比于同条件纯组分PpPD(11.25F/g)以及等氧化当量FeCl3与H2O2氧化剂制备的PpPD/GO(176.25F/g)材料,PpPD/GO/Au纳米复合材料的电化学性能最优,比电容可达到237.5F/g,充分说明PpPD/GO/Au三重复合材料形成的积极意义。
A novel conductive nanocomposite named poly(p-phenylenediamine)/graphene oxide/Au(PpPD/GO/Au) was synthesized via in situ polymerization using p-phenylenediamine(p-PDA) as monomer and HAuCl4 as oxidants and Au sources in the presence of graphene oxide(GO).The microstructure of the nanocomposite was characterized by FESEM,FT-IR and XRD patterns.And the results show that three phases including PpPD,GO and Au nanoparticles exist.Compared with single phase of PpPD or GO,the heat stability of the nanocomposite is improved greatly.And the highest specific capacitance of 237.5F/g can be obtained from the PpPD/GO/Au nanocomposite,which is higher than 11.25F/g of individual PpPD and 176.25F/g of PpPD/GO obtained by using FeCl3 and H2O2 as oxidants in the same condition.Obviously the specific capacitance of nanocomposite is improved significantly,which shows positive meanings in this field.
