摘　　要：周期性阵列结构纳米材料广泛应用于材料化学、能源储存、光子学、分子传感、生物医学等领域。采用溶液法制备了平均直径为1.45μm、单分散性较好的氨基化聚苯乙烯(aminated polystyrene,aPS)微球;以普通非导电性载玻片为支撑基板,利用旋转涂覆法,通过改变旋涂时间、旋转速度、aPS微球的固含量等,成功将aPS微球制备成单层规整排列的阵列结构。该阵列结构具有预期的单层结构,aPS微球呈现良好的周期性排列,整体结构可以看作是周期性排列的微球阵列。并以此作为合成模板,采用稀溶液合成法,将聚苯胺(polyaniline,PANI)原位生长在aPS微球阵列上,得到具有规整排列的PANI@aPS微球阵列。通过染料罗丹明6G(R6G)吸附实验发现,未氨基化的PS微球、aPS微球阵列,纯PANI和PANI@aPS微球阵列对R6G的饱和吸附量分别约为1.3、2.0、5.0和7.1 mg/g,表明PANI@aPS微球阵列对R6G具有较好的吸附性。与提拉膜等规整排列技术相比,该方法更为便捷,容易在一般实验室实现,可以为金属纳米粒子(Au和Ag)、无机化合物和导电聚合物的规整生长提供模板。Nanomaterials with periodic array structures are widely used in material chemistry,energy storage,photonics,molecular sensing,biomedicine and other fields.In this paper,the aminoated polystyrene(aPS)microspheres with the average diameter of 1.45μm and good monodispersity were prepared by solution method.And then,the aPS microspheres were successfully prepared into a single-layer array structure onto the ordinary non-conductive glass slide by changing the spin coating time,rotation speed,solid content of aPS microspheres,etc.The array structure had the expected monolayer structure,and the aPS microspheres showed a good periodic arrangement.The overall structure can be seen as a periodically arranged microsphere arrays.With this as the synthesis template,polyaniline(PANI)was in-situ grown on the aPS microsphere arrays using the dilute solution synthesis method to obtain PANI@aPS microspheres arrays.The dye rhodamine 6G(R6G)adsorption experiments found that the saturated adsorption capacity of unaminated PS microspheres,aPS microsphere arrays,pure PANI and PANI@aPS microsphere arrays on R6G were about 1.3,2.0,5.0 and 7.1 mg/g,respectively,indicating that the PANI@aPS microsphere array has good adsorption to R6G.Compared with the regular arrangement technology such as the pulling film arrangement,this method was more convenient and easier to implement in general laboratories,and it could provide templates for the regular growth of many metal nanoparticles(such as Au and Ag),inorganic compounds and conductive polymers.
