| 摘 要： | 基于自组装技术制备了3种不同粒径的聚苯乙烯微球阵列,并翻制了与微球阵列互补的软模板.基于室温无外压的转移印刷技术制备了聚甲基丙烯酸甲酯半球形微纳阵列,然后基于原位光还原技术在聚甲基丙烯酸甲酯半球表面制备Ag纳米颗粒,构筑了拉曼增强的半球状多级Ag基底.转移印刷技术的关键是利用软模板自身的低表面能和表面羟基化的图案化材料与亲水基底界面间的氢键作用力.

| Abstract: | PS microsphere arrays with three kinds of particle sizes, which were used to make soft templates, were fabricated by self-assembling. Then, the polymethyl methacrylate ( PMMA) hemispherical arrays were transferred from the soft template onto the substrate under ambient temperature with no pressure. Ag nanoparticles were formed by photo-reduction on the surface of hemispherical arrays, which performed surface enhanced Raman scattering. The key to this successful transfer imprinting is that the low surface energy of soft template and the hydrogen bond of the interface between PMMA and the substrate. |
