Abstract Details

2000, MS, University of Cincinnati, Engineering : Materials Science.
A novel electroless plating method had been employed to coat a silver film onto the inner surface of porous alumina substrate. While the original substrate was a very good insulator, the coated substrate became highly conductive. One of the possible applications of this coated porous material is to serve as a novel electrical charged filter (ECF). An evenly distributed silver film with a thickness of a few tens of micrometers had been successfully produced by the electroless plating method. Silver growth process was investigated to analyze its kinetics. The change of overall conductivity of the coated substrate with time was studied. An empirical equation was developed to fit the experimental data. Based on the physical model of the coating kinetics, the process was simulated animatedly by computer simulation. The morphology and other properties of the film was investigated by using SEM, XRD and other means. The newly formed film was found to have very weak bonding strength with the substrate. Annealing treatment was adopted to enhance the bonding. Experiments showed that while higher annealing temperature gave rise to higher bonding strength, the conductivity decreased. An optimized annealing condition was determined based on experimental results. The change in conductivity caused by annealing was attributed to the morphology change of the film. Preliminary experiments on water treatment capability of Electrical Charged Filter were also carried out and the results supported the validity of the ECF concept.
