    Abstract: 在這項研究中,我們開發了一個三維模板,通過雙團鏈共聚高分子自組裝的BCP奈米結構,進行表面重建以獲得多孔高分子薄膜。,進一步用於製造銀奈米結構之模板。三維多孔模板用晶種成長法成長銀晶種後使用氯化亞錫致敏,亞錫離子吸附至模板表面上,通過銀鏡反應生長具有高密度的銀奈米結構顆粒。三維銀奈米結構可用於表面增強拉曼光譜(SERS)的優異基材,用於物理吸附羅丹明6G的分子傳感測。在模板表面上存在豐富的銀奈米顆粒在通過電磁機制促進在拉曼增強中起關鍵作用。基於自組裝雙團鏈共聚高分子奈米構造的銀模板為製造SERS基材提供了新的設計策略。;In this study a three-dimensional template was generated through surface–reconstruction of self-assembled PS-b-P4VP nanodomains for fabricating nanostructured silver particles. The three-dimensional porous template was sensitized with stannous chloride, by which silver tiny seeds were first nucleated onto the surface of the nanodomains. Silver nanostructured particles with a high number density were grown by silver mirror reactions. The three-dimensional silver nanostructures can be used as an excellent substrate for surface-enhanced Raman spectroscopy (SERS), coupled with fluorescence quenching, which allows for molecular sensing of physically adsorbed Rhodamine 6G. The presence of abundant silver nanoparticles on the surface of the template plays a critical role in promoting a large Raman enhancement via an electromagnetic mechanism. The silver template based on the construction of self-assembled BCP nanodomains provides a new design strategy for fabricating SERS substrates.
