我们证明了成功的制造的多层纳米结构的交替纯聚合物laminates和含金纳米颗粒laminates，都在纳米厚度，通过利用对称的聚苯乙烯嵌段聚（4-乙烯基吡啶），PS-b-P4 VP的薄膜。P4 VP嵌段与衬底之间的强相互作用和PS嵌段的较低表面能产生平行于衬底的具有不对称润湿配置的多层层状结构。然后，在P4 VP层中选择性地合成金纳米颗粒，而不改变多层结构。通过透射电子显微镜证实了交替的聚合物和金纳米颗粒的薄膜。由于采用自组装聚合物，多层纳米结构有效地制造而无需逐层过程。
We demonstrated successful fabrication of a multilayered nanostructure of alternating pure polymeric lamellae and gold nanoparticle-containing lamellae, both in a nanometer thickness, by utilization of thin films of symmetric polystyrene-block-poly(4-vinylpyridine), PS-b-P4VP. The strong interaction between the P4VP block and the substrate and lower surface energy of the PS block generated a multilayer of lamellae parallel to the substrate with an asymmetric wetting configuration. Then, gold nanoparticles were synthesized selectively in the P4VP lamellae without altering the multilayered structure. The thin film of alternating polymers and gold nanoparticles was confirmed by transmission electron microscopy. Since self-assembling polymers were employed, the multilayered nanostructure was effectively fabricated without a layer-by-layer process.
