為了賦予聚胺基甲酸酯更多不同的功能及更加良好的物理性質，本研究利用高分子合成的概念將無機奈米材料 (halloysite nanotubes; HNTs以及奈米銀)添加至聚胺基甲酸酯 (Polyurethane; PU)中，並探討奈米無機材料對聚胺酯性質的影響。本研究分為兩部份。
第一部份為利用4,4’-diphenylmethane diisocyanate (MDI)、polytetramethylene glycol (PTMG)與含吡啶環之2,6-pyridinedimethanol (2,6-PDM)製備出形狀記憶聚胺基甲酸酯 (Shape memory polyurethane; SMPU)，再將不同比例之HNTs混摻於PU內製備出形狀記憶型HNTs/PU奈米複合薄膜，隨後利用FTIR、TEM、XRD進行HNT於PU中分散性的探討，而HNTs/PU的熱穩定性與黏彈性使用TGA、DSC、DMA鑑定，再使用萬能拉伸機鑑定HNTs/PU的機械性質與形狀記憶性，最後利用AFM、WCA探討HNTs/PU薄膜表面粗糙度與親疏水能力，結果說明當Halloysite添加至PU內能夠提升PU的熱穩定性、機械性質與形狀記憶測試，結果揭示HNTs/PU-3形狀恢復能夠達到98%以上。
第二部份使用Halloysite、硝酸銀 (AgNO3)以及聚乙烯吡咯烷酮 (PVP)在Halloysite粉末上進行銀的包覆則形成Ag/HNTs。接著利用4,4’-diphenylmethane diisocyanate (MDI)、polytetramethylene glycol (PTMG)作為硬鏈段與軟鏈段、使用2,6-pyridinedimethanol (2,6-PDM)作為鏈延長劑製備出聚胺基甲酸酯 (PU)，再將不同比例之鍍銀Halloysite nanotubes (Ag/HNTs)混摻於PU內製備出Ag/HNTs/PUs奈米複合薄膜。首先利用EDS、XRD、TEM對Ag/HNTs粉末進行銀於HNTs的附著情況之分析，隨後利用FTIR進行Ag/HNTs於PU中分散性的探討，Ag/HNTs/PU的熱穩定性與黏彈性使用TGA、DSC、DMA鑑定，再使用萬能強力試驗機鑑定Ag/HNTs/PU的機械性質，接著利用AFM、WCA探討Ag/HNTs/PU薄膜表面粗糙度與親疏水能力，最後進行對大腸桿菌的抗菌測試，結果說明當Ag/HNTs添加至聚胺酯內能夠提升PU的熱穩定性、機械性，在抗菌測試上說明Ag/HNTs粉末能夠提升聚胺酯的抗菌活性。

In order to give the polyurethane more different functions and better physical properties, this study used the concept of polymer synthesis to synthesize the nano inorganic materials (halloysite nanotubes; HNTs & nanosilver particles) into polyurethane (PU), and then discuss the effect of nano inorganic materials on the properties of polyurethane. This study is divided into two parts.
The first part is using 4,4'-diphenylmethane diisocyanate (MDI), polytetramethylene glycol (PTMG) and 2,6-pyridinedimethanol (2,6-PDM) containing pyridine ring to prepare shape memory polyurethane (SMPU), and then mix different proportions of HNTs into PU to prepare HNTs/PU nanocomposite film. Use FTIR, TEM, XRD to discuss the dispersion of HNT in PU, and the thermal stability and viscoelasticity of HNTs/PUs are evaluated by TGA, DSC, DMA, and then the universal tensile machine is used to identify the mechanical properties and shape memory of HNTs/PUs. Finally, AFM and WCA are used to discuss the surface roughness and hydrophobicity of HNTs/PUs films. The results show that when halloysite is added to the PU, it can improve the thermal stability, mechanical properties and the shape memory properties. The results reveal that the shape recovery of HNTs/PU-3 can reach more than 98%.
The second part uses halloysite, silver nitrate (AgNO3) and polyvinylpyrrolidone (PVP) to prepare doped-silver halloysite powder (Ag/HNTs). Then, using 4,4'-diphenylmethane diisocyanate (MDI) and polytetramethylene glycol (PTMG) as the hard segment and soft segment, using 2,6-pyridinedimethanol (2,6-PDM) as the chain extender to prepare polyurethane (PU), and then mix doped-silver halloysite nanotubes (Ag/HNTs) with different proportions into PU to prepare Ag/HNTs/PUs nanocomposite film. First, EDS, XRD, and TEM were using to analyze the adhesion of Ag/HNTs powder on the halloysite. Then, FTIR was used to discuss the dispersion of Ag/HNTs in PU. The thermal stability and viscoelasticity of Ag/HNTs/PU were using TGA, DSC, DMA to measure, and then use the universal strength test machine to measure the mechanical properties of Ag/HNTs/PU, then using AFM, WCA to explore the surface roughness and hydrophobicity of Ag/HNTs/PU film. Finally carry out the against E. coli’s antibacterial test. The test results show that when Ag/HNTs are added to the polyurethane, the thermal stability, mechanical properties and the antibacterial test shows that Ag/HNTs powder can enhance the antibacterial activity of polyurethane.
