奈米二氧化鈦在織品上的應用廣泛。本篇論文主要分為兩個部分，第一部分是製備附著二氧化鈦奈米材料的纖維。以四丁基鈦和冰醋酸為前驅物，利用水熱法製成二氧化鈦溶液，將纖維基材浸漬於二氧化鈦溶液中，經壓吸機壓吸後烘乾將二氧化鈦均勻的分散附著於各種纖維基材上。經X-射線繞射儀(XRD)及掃描式電子顯微鏡(SEM)證實纖維基材上有銳鈦礦相二氧化鈦的吸附。
第二部分主要研究使用四氯金酸當作金的前驅物，與水熱法製備所得二氧化鈦及商業型DP25作為觸媒載體，利用光還原法製備金/二氧化鈦奈米觸媒。由TEM穿透式電子顯微鏡得知在pH值10時還原在銳鈦礦相二氧化鈦上的奈米金粒徑為5~ 6 nm (銳鈦礦相二氧化鈦粒徑為15~20 nm)，而還原在DP25二氧化鈦上的奈米金粒徑為3~5 nm (DP25二氧化鈦粒徑為30~50 nm)。這兩種金/二氧化鈦奈米材料經過工業用的分散劑及潤濕劑配合超音波振盪，再經壓吸法後可成功將金/二氧化鈦均勻的分散附著於聚乙烯/聚酯不織布和聚酯/聚丙烯不織布上。

Nano titanium dioxide (TiO2) is widely used on the textile materials. This thesis is divided into two parts. The first part is to deposite home-made TiO2 nanoparticles on fabric substrates. A TiO2 sol was prepared by hydrothermal method using titanium (IV) n-butoxide as the precursor of titanium. Fabric substrates including PP, PET/PP, PET/PAN, and Nylon were impregnated in the TiO2 sol followed by pressure-suction process to uniformly disperse TiO2 onto the fabric substrates. The X-ray diffraction (XRD) and scanning electron microscopy (SEM) confirmed adsorption of anatase TiO2 on fabric substrates.
The second part of this work is to synthesize Au-TiO2 nanoparticles by photoreduction method using HAuCl4 as Au precursor, and commercial DP25 TiO2 and home-made anatase TiO2 as catalyst subatrates. Transmission electron microscopy (TEM) showed that at pH value of 10, the gold nanoparticles with size of 5 ~ 6 nm can be reduced on the anatase TiO2 (size 15 ~ 20 nm), while the gold nanoparticles with size of 3 ~ 5 nm can be reduced on the anatase titanium dioxide (size 30 ~ 50 nm). The Au-TiO2 samples mixing with industrial grade dispersant and wetting agent in conjunction with ultrasonic oscillation, and then used the pressure-suction method to successfully dispersed Au-TiO2 uniformly onto the polyethylene/polyester non-woven and polyester/polypropylene non-woven subtrates.
