因具有多层次、多维度、多组分的耦合和协同效应,分级异质结构纳米材料的设计与制备已成人们关注的热点。利用氧化石墨烯(GO)的大比表面积片状结构的特点,通过原位低温聚合在其表面制备出聚苯胺(PANI)的纳米阵列,形成以GO为核层,PANI为壳层的GO@PANI微粒。分别研究反应时间、PANI添加量、掺杂酸浓度对GO@PNAI表面形貌的影响。在此基础上,探索GO@PNAI的生成机理,为GO@PNAI分级异质核壳材料的可控制备提供了理论依据。
Because of its multi-level,multi-dimensional,multi-component coupling and synergistic effect,the design and preparation of heterostructure nanomaterials attracted many attention.GO@PANI particles with graphene as the core layer and polyaniline as the shell were prepared by in-situ low-temperature polymerization.The effects of reaction time,PANI addition amount and doped acid concentration on the surface morphology of GO@PNAI were studied.On this basis,the growth mechanism of PNAI nanorods was explored.This work may provide a basis for the controllable preparation of GO@PNAI heterogeneous core-shell materials.
