Firstly, we report the preparation of TiO2 nanotube array by potentiostactic anodizing process. Titanium foil was anodizing in a glycerol and ethylene glycol solution containing NH4F at different voltages and temperatures to fabricate highly ordered TiO2 nanotube array. SEM and TEM photographs, show the morphology and hollow tubular structure of TiO2 nanotube arrays. The pore diameter drops from 100 nm to 30 nm along with the operating voltage reduces from 50 V to 20 V in ethylene glycol solution at room temperature. While keeping the same pore diameter, the length of nanotubes grow from 40 μm to 126 μm along with the temperature increases from 20 ℃ to 40 ℃under the operating voltage of 50 V in ethylene glycol solution. Additionally, the products was characterized by EDX, SAED, UV and XRD to demonstrate that TiO2-anatase structure is formed upon thermal annealing after anodization. Secondly, the regioregular poly(3-hexylthiophene) (P3HT) is infiltrated into the nanotubes to form the composite materials. The charge transfer properties of the P3HT/TiO2 composite materials can be monitored by photoluminescence quenching. After excitation at 430 nm, the PL quenching efficiencies follow the order: P3HT/TiO2 nanotube array consist of 30 nm pore > P3HT/TiO2 nanotube array consist of 100 nm pore diameter>P3HT/TiO2 nanoparticles. The result indicates an effective charge transfer from P3HT to TiO2 nanotube array of smaller pore diameter. Sze-Ming Yang 楊思明 2008 學位論文 ; thesis 82 zh-TW
