Influence of Laser Ablation on the Oxygen Permeability of Ba_(0.5)Sr_(0.5)Co_(0.8)Fe_(0.2)O_(3-δ) Membranes

摘要

After laser ablation treatment, there are grooves on the surfaces of Ba_(0.5)Sr_(0.5)Co_(0.8)Fe_(0.2)O_(3-δ) (BSCFO) membranes. These grooves with width about 150μm and depth about 25μm increase the specific surface of these membranes. The oxygen permeation fluxes through these membranes, which sides were treatment by laser ablation, were measured. Comparing with the membrane without laser ablation treatment, the oxygen permeation fluxes through the membranes with cross grooves pattern decorated on both sides after laser ablation treatment can increase by 34.7%.
