In order to solve the transmission system problems of Flashover, Ni2+ doped TiO2 thin film and pure TiO2 thin film were prepared by sol-gel method. The crystalline phase and morphology were characterized by XRD and AFM, and static contact angle measurement was employed to estimate the wettability of prepared films. The results indicate that a small amount of Ni2+ doped TiO2 thin film makes hydrophilicity...
A magnetically separated fly ash micro-sphere (MSFM) were prepared by citrate sol-gel process.The microstructure of the products were tested by SEM and EDS. It was found that the MSFM was coated with network of barium ferrite, which exhibited the magnetic absorption property. Then the TiO2 film photocatalysts immobilized on MSFM were prepared by sol-gel method, methods. The crystal phase and morphology...
TiO2 films were prepared on glass substrates by sol-gel process for dye-sensitized solar cell application. TiO2 sol was prepared by the hydrolysis/polycondensation. Titanium(IV) tetra isopropoxide (TTIP) was used as precursor and Nitric acid (HNO3) was used as a catalyst for the peptization. The crystal structure and morphology of prepared materials were characterized by XRD, SEM. The observations...
TiO2 films were deposited on different substrates such as SiNx/Si, SiOx/Si, Si and Ge by a sol-gel method. The structural properties of the films were investigated by XRD, SEM and XPS. The results showed that the substrates played a crucial role in the crystalline quality and materials stoichiometry of sol-gel derived TiO2 films. Especially, the film deposited on SiNx/Si substrate had a better crystalline...
The processes for the physical vapor deposition (PVD) of Pb(Zr,Ti)O3 (PZT) thin films from two different composite oxide targets has been demonstrated. PZT thin films have been deposited by both PVD or sputter technique and standard sol-gel method. Half micron PZT films were deposited by both methods on identical substrates (Si[(100) 4 inch Cz wafer]/SiO2/Ti-TiO2/Pt) followed by sputter-deposited...
A novel piezoelectric microbalance biosensor based on nano-crystalline PZT/quarts is fabricated. Sol-gel method is utilized to bond the PZT thin films on the quartz substrate as the sensing unit. The microstructure and the surface appearance of PZT thin films on quartz substrate and the influence of cancer cells detecting with the sensing unit using PZT/quartz are studied. The XRD and AFM results...
Development of organic and inorganic composites has grown in recent years due to a wide range of potential use of these materials. The aim of this research is to investigate the effect of Pani additions on the TiO2 based thin film as VOC gas sensing properties. TiO2 were prepared using sol gel technique. Up to 3 wt% of Pani were directly added to the TiO2 solution. 3 layers of TiO2/Pani solution mixture...
The effect of the ZnO homo-buffer layer on the structural, optical and electrical properties of the Sol-gel ZnO films was systematically investigated. The XRD and SEM results show that the homo-buffer layer can improve the degree of the preferential c-axis orientation (the best Lotering orientation factor (F) can reach 0.915), the grain size and the surface morphology of thereon ZnO films. A narrower...
