水性聚胺基甲酸酯-奈米金複合膜之製備與性質分析

Preparation and characterization of waterborn polyurethane-nanogold composite films

指導教授 : 張朝欽

摘要


本研究成功的製備出兩種系列的水性聚胺基甲酸酯-奈米金複合膜。第一種是分別以1,4-BD與1-thioglycerol為鏈延長劑來合成水性聚胺基甲酸酯微球,以其作為保護劑來還原金鹽,利用相關官能基與奈米金鍵結,製備水性聚胺基甲酸酯-奈米金複合膜,再以UV-vis和TEM來証實奈米金的形成。另外一種奈米金複合膜除使用1,4-BD外還使用含羥基硫醇包覆的奈米金作為鏈延長劑,將奈米金以共價鍵的方式結合在水性聚胺基甲酸酯-奈米金複合膜中。利用不同製備方式與不同含量的奈米金形成的複合膜,來討論奈米金對於複合膜結構與性質的影響。 利用TEM與DLS來分析PU微球,以1-thioglycero1為鏈延長劑的水性聚胺基甲酸酯會因含有硫醇官能基使微球的分散穩定性較好,而有奈米金存在會提升分散的穩定性。再以 AFM、EDXS、SEM、ESCA FT-IR、EA、GPC與UV-vis觀察複合膜的形態與結構,以及使用TGA、DMA及應力-應變測試來分析複合膜的性質。

並列摘要


Two series of waterborn polyurethane-nanogold composite films were prepared successfully in this study. In the first series, two different chain extenders, 1,4-butyldiol and 1-thioglycerol, were separately used to synthesis the distinct main-chain of waterborn polyurethane microspheres. The presence of the polyurethane protected the gold nanoparticles, and the formation of gold nanoparticles was confirmed by means of UV–vis and TEM. In another series, the composite films were prepared by using two chain extenders, 1,4-butyldiol and hydroxy-containing thiol-coated gold, at the same time. The nanogold bonded in the waterborn polyurethane structure by the covalent bond.   TEM and DLS results showed that waterborn polyurethane microspheres, containing thiol functional groups have the better dispersive stability. The presence of nanogold can improve the dispersive stability of the microspheres. AFM, EDXS, SEM, ESCA, FT-IR, EA, GPC, and UV-vis examined the morphology and structure of the prepared composite films. TGA, DMA and stress-strain tests characterized the properties of composite films.
