硫醇苯胺共聚物/奈米金複合膜材暨奈米碳管/奈米金複合物之製備與性質研究
Preparation and Properties of Nano-Gold Attached Mercaptoaniline Complex Membrane and Carbon Nanotubes/Nano-Gold Particles Composites
摘要
摘要 在本論文中，將以硫醇苯胺共聚物(ANI+MANI)/奈米金複合膜材及奈米碳管/奈米金複合物進行研究與性質探討，並利用各種儀器作基本鑑定及性質上之量測分析。 於第三章中，利用苯胺及硫醇苯胺兩種單體進行氧化聚合來合成共聚物，並將之製備成為薄膜，再將薄膜整片浸泡到預先以水熱法合成之水相奈米金當中，由於薄膜表面含有硫醇(-SH)之官能基，又加上硫本身對金粒子具有良好之選擇性，因此易形成配位共價鍵(ligand to metal, -S-Au) 1。經由AFM證實硫醇苯胺共聚物(ANI+MANI)/奈米金複合膜材其表面平滑度有提高的趨勢，又藉由接觸角量測證實了硫醇苯胺共聚物(ANI+MANI)/奈米金複合膜材是很好的疏水性材料。 於第四章中，成功地利用了硫醇苯胺(2-Mercaptoaniline)將奈米碳管表面做一個化學修飾，再與奈米金反應，此一方法是利用硫醇苯胺(2-Mercaptoaniline)這個分子當作一個架橋基，將奈米碳管與奈米金之間做一個聯繫，所得到的複合物將透過穿透式電子顯微鏡FTIR-ATR、UV-visible、Raman spectroscopy以及X-ray繞射儀做一個鑑定。

Abstract In this Master dissertation, we have preparation and properties of nano-gold attached mercaptoaniline complex membrane and carbon nanotubes/nano gold particles composites, respectively. They were studied on the optical clarity and other properties discussion. For chapter 3, Poly (ANI-co-MANI)/Au composite film was prepared by a facial process with well-dispersed on its surface. The hydrosulfide group (-SH) contained by the Poly (ANI-co-MANI) was play an important role as a bridge base on the -S-Au bonding. This bond is well-known to react and form easily so that a original procedure has been developed. This advantageous consequence would be helpful for practical manipulation, in particle for the biosensor and bio-catalysis devices. For chapter 4, we present the novel assemblies by anchoring gold nanoparticles of ~ 10 nm diameter to sidewalls and ends of carbon nanotubes (CNTs) via covalent interaction between gold nanoparticles and thiol-terminated CNT surfaces. Mercaptoaniline was first grafted onto the surface of nanotubes by covalent interaction between primary amine groups of mercaptoaniline and carbon nanotube surface to give thiol-terminated CNTs. Subsequently, gold nanoparticles were anchored to the surface of nanotubes through covalent interaction between thiol-terminated nanotubes and gold nanoparticles. This new assemblies of carbon nanotubes (CNT) and gold nanoparticles were obtained with mercaptoaniline as molecular bridge. These assemblies were confirmed further by transmission electron microscopy, FTIR-ATR, UV-visible, Raman spectroscopy and X-ray powder diffraction.
