Abstract

Abstract: A kind of photo sensitive ceramic inks is was developed for Direct-WriteAssembly (DWA).A TiO₂based photolysisdevice of wood pile structure whose with filament diameter of is around 270 μm was fabricated through this method. The preparation of the photo sensitive ink and the principle of the DWA were investigated in order to obtain ink with proper rheology. XRD and TEM were used to characterize the phase and morphology of the TiO₂ powder in the ink. Optics microscope is was appliedto analyze the internal architecture and typical size of the wood pile structure. The sample immersed in methylene-blue solution is was radiated under UV-light for 20 min and the transmittance of the solution measured byUV-Vis spectrophotometer. Under the UV-light irradiation for 10minutes, ,the degradation rate of methylene blue solution with initial concentration of4mg/L is was 76%, and then increases increased to91% fora 20 minutes’ after UV radiation for 20 min. We also use SEM was usedto study the filament surface morphology of the woodpile and investigatethe enhancement mechanism of the high photolysis performance based on these results.The effective photolysis performance can be attributed to the 3D woodpilestructure with rough porous surface, which greatly increases the area of the photocatalysisreaction.
