摘要

由於低成本且製作簡單，將奈米粒子沉積於紙上在生醫檢測上開闢了新的應用領域。在本論文中，我們試圖將沉積氧化鋅與銀奈米粒子跟纖維紙結合形成氧化鋅紙與銀紙，並對其做特性量測。我們使用醋酸鋅與氫氧化鈉化學還原法製備氧化鋅紙、硝酸鋅與硼氰化鈉化學還原法製備銀紙。再氧化鋅紙的備製中，本論文中也提出使用噴塗機先在纖維紙上成長氧化鋅種晶層(ZnO seed layer)後再使用化學還原法製備氧化鋅紙，並以沉積時間50小時之氧化鋅紙製備出氧化鋅+銀紙。經由掃瞄式電子顯微鏡(Scanning Electron Microscopy，SEM)確認了氧化鋅及銀奈米粒成長於纖維紙上，其上之氧化鋅奈米粒子粒徑大約14nm ~ 39nm，而銀奈米粒子粒徑大約28nm ~ 57nm，氧化鋅混合銀奈米粒子之粒徑大約31nm ~ 66nm。透過能量色散X射線光譜儀(Energy-dispersive X-ray spectroscope，EDX)的分析，可發現氧化鋅紙之主要材料為Zn與O，銀紙之主要材料為Ag。再由X光繞射儀(X-Ray Diffraction，XRD)之分析，可發現氧化鋅紙之晶體結構主要晶向在(100)與(101)，而銀紙之晶體結構主要晶向在(111)。對於氧化鋅/銀紙，經EDX可發現其主要材料同時包含了氧化鋅與銀，而XRD的分析也確認氧化鋅+銀紙之主要晶向為(100)的氧化鋅及(111)的銀。

Depositing nanoparticles on paper has opened new area of application in biomedical testing due to its low-cost and easy fabrication. In this thesis, attempt has been made to deposit ZnO nanoparticles, Ag nanoparticles and ZnO + Ag nanoparticles on cellulose paper and characterize those nanoparticles on cellulose paper. Chemical reduction of zinc acetate dehydrate and sodium hydroxide were adopted for the deposition of ZnO, while that of AgNO3 and NaBH4 were for the deposition of Ag nanoparticles on cellulose paper. In particular, we proposed to use spray pyrolysis for the first time to prepare the ZnO seed layer for ZnO paper fabrication, and ZnO paper for fifty hours of deposition time for the fabrication of ZnO + Ag paper. By using the scanning electron microscopy (SEM), we confirmed that ZnO nanoparticles and Ag nanoparticels were successfully deposited on the cellulose paper. It is found that the average diameter of ZnO nanoparticles on cellulose paper was about 14 nm - 39nm, while that of Ag diameter on cellulose paper was about 28nm - 57nm, and that of ZnO + Ag nanoparticles paper was about 31nm - 66nm. Energy-dispersive X-ray spectroscopy (EDX) results show that deposited materials are composed of Zn and O for ZnO paper, and Ag for Ag paper. From the X-ray diffraction (XRD) spectra of the ZnO paper, it is found that the preferential orientation of the deposited ZnO nanoparticles on cellulose paper is (100) and (101), while that of the deposited Ag particles on cellulose paper is (111). For ZnO + Ag paper, the EDX analysis result confirms that the deposited materials include both the ZnO and Ag, and its XRD result shows that the preferential orientations are (100) ZnO and (111) Ag.
