Abstract：Using ZnCl2 or Zn(NO3)2 as materials, the ZnO films were prepared by ultrasonic deposition method on the surface of titanium sheet.The results show that ZnO is hexagonal wurtzite structure, and the microstructure of ZnO thin films is affected by the kind of raw materials and ultrasonic time.At the ultrasonic time of 3 h, ZnO film prepared from ZnCl2 is thick, and a part of ZnO exists nano wires with loose accumulating.The ZnO thin films prepared from Zn(NO3)2 is thin, and most ZnO nanoparticles loose piled on the surface of the substrate, however few particles are nanorods.When the ultrasonic time is 6 h, the deposition quantity of ZnO film prepared from Zn(NO3)2 is increased, and many ZnO is nanorods.Meanwhile, the particles are irregularly stacked on the surface of the substrate which was wire mesh linked together as network-like.After the hydrophobic modification of 48 h by stearic acid-ethanol solution, the titanium sheet and ZnO films are changed from hydrophilicity to hydrophobicity.After ultrasonic depositing for 3 h, the hydrophobicity of ZnO film prepared from Zn(NO3)2 is stronger than that prepared from ZnCl2, and its antibiofilm properties on Shewanella putrefaciens biofilm is higher than the latter.However, the ultrasonic time is 6 h, the deposition quantity of ZnO film is large, and its antibiofilm propertiy is better due to its antibacterial properties of the sample.
