碩士 === 國立臺灣師範大學 === 工業教育學系 === 103 === In this research, the titanium dioxide (TiO2) photocatalyst film deposited on stainless steel plates by electrodeposition technique , and it is useful for photocatalyst products development. Electrodeposition processes used by the working fluid mixing with diluted alcohol to produce peroxotitanic acid bath by sol-gel method , so titanate ions deposited on the 304SS stainless steel plates that made of nano photocatalyst film, and then it would strengthen crystallization in the photocatalyst film by annealing, detection the surface morphology、Photocatalytic and hydrophilic properties such as hydrophilicity . Using XRD, HR-FE SEM, surface profiler and other equipment to performed made from the parameters measured and analyzed the relationship between film properties, chosen a suitable coating parameters, used as following research of the reference. In the electrodeposition process, for the parameters of different voltage and deposition tim、surface properties of the deposited films and materials to discussion,then using annealing method to observe changes in the crystal case. In photocatalytic , analysis of the situation before and after the modification of the photocatalyst as UV, discussion after irradiation with UV light contact angle changes.The results showed, under the control of voltage and deposition time conditions, the deposited film can be obtained, but the watch by SEM, the surface is not complete.rather through annealing process, we can get a clear crystal particles. rather test pieces in the photocatalytic coating experiments, according to displayed after the light the reflectance a decrease, the display characteristics of the anti-UV coating increase. While in terms of the contact angle measurements, when not as ultraviolet light can reach 41.91 degrees, TiO2 thin films prepared also prove a hydrophobic The research can provide the future production of the titanium dioxide (TiO2) photocatalyst film deposited on 304SS stainless steel plates to reference and set with stainless steel strainer in air conditioning systems to improve their antimicrobial decontamination capabilities.
